How to knit a Basic Beanie without a pattern – Part 1: Brim and Body

I have read several Facebook posts and Ravelry forums where new knitters are asking about how to knit a basic hat. There are many basic beanie style hat patterns available for free on Ravelry, including one of mine: Basic Beanie Hat.

But the truth is that a basic beanie hat is fairly easy to knit without any pattern if you are familiar with its structure and know your gauge for the yarn you want to use for the hat. So this post is about the basic structure of a beanie, knit in the round.

Now, a beanie can be knit top down or bottom up, but if you look at most patterns, they are written with a bottom-up construction and this will be the approach I will follow here. There are three parts to a basic beanie: The brim, the body, and the crown. The brim of a beanie is usually done in either 1×1 ribbing (k1,p1) or 2×2 ribbing (k2,p2). The length of the brim can be relatively short – and intended to not be folded, or it can be longer so that it will be worn with the brim folded.

The body of a beanie is the part of the hat that covers the head from just above the ears to where the crown is formed. The length of the body varies according to the size of the hat, with children’s hats being shorter than an adults’ and Men’s hats are usually longer than Women’s. For a basic beanie this length is approximately the length from the top of the head to the bottom of the earlobe or half the length of measuring from the bottom of one earlobe to the other up over the top of the head.  

The crown of a beanie is the area that covers the top of the head and is shaped by making decreases to form a circle that is closed at the very top.

To begin knitting the basic beanie you need to do a little math. You need to know what circumference you want it to be. If you have the measurement of the circumference of the head of person you want to fit, you can use that. If you don’t know the circumference, then you can use a standard size chart for the measurements. See the chart below. For a women’s head, I usually use a circumference of 21 – 22 inches as a starting point.

Knitted beanies are made with negative ease. Now what do I mean by that? Negative ease means that the knitted hat will be smaller than the actual circumference and I usually factor in about 10% negative ease for my beanies. This gives the hat a good fit and it hugs the wearer’s head and stays in place. Using an example of a 21 inch circumference, the knitted circumference with 10% negative ease is 19 inches. (10% of 21 = 2.1; 21-2 = 19 or if you prefer: 21 x 0.9 = 19)

You are now ready to determine how many stitches to cast on to start the brim of the beanie. For this you will need your stitch gauge in stitches per inch (spi). I usually have a gauge of 5 spi with worsted weight yarn, so in this example, I multiply 19 inches by 5 sts which gives me 95 sts. However, if I am doing 1×1 ribbing, I need an even number of stitches, so I can either round down to 94 or round up to 96 sts. If I do 2×2 ribbing, I need an even number of stitches, but the number also has to be divisible by 4. In this example, 96 is divisible by 4, so I would start with 96.

For a Women’s beanie, I usually like to knit the ribbing to a length of approximately 2 inches and then start the body. For a basic beanie, I knit the body in stockinette stitch. The body area is where you can add various textured stitch patterns or knit stripes using different colors of yarn. But the very basic beanie is knit in stockinette stitch.

The length of the hat is determined by measuring the length of the wearer’s head from the lower earlobe to the top of the crown. Another way is to measure the head from the bottom of one earlobe over the top of the head to the bottom of the other earlobe and then divide that number by 2. For a women’s hat, I usually use a length of 10.5 to 11 inches, for a men’s hat I use 11 to 11.5 inches. See the standard size chart above for further information. The crown of the hat is approximately 1/3 of the total length of the hat. So, once the ribbing is done, you knit the body to the desired length where the crown shaping starts (measured from the cast on edge). In my example of a women’s hat with a total length of 11 inches, I would knit to a length of 7.5inches. The remaining length of the hat is where the crown is shaped using decreases.

My next post covers things you need to consider to knit the crown of the beanie.

WIP: Socks for DSWIP: Socks for DS

My DS put “socks that won’t wear out at the heels” on his Christmas list. It was a late request – and not one that would I would likely be able to meet by Christmas – but it was an invitation to knit socks for someone I love!

MattsSocks_Foot2So – I started a pair of socks – plain label version, cuff-down with 2 X 2 ribbing for the heel and instep. I used Knit Picks Stoll in Carbon Twist colorway. I got about 6 inches of the cuff done before Christmas and so I wrapped the “in progress” socks up along with two additional balls of yarn (Knit Picks Stoll – Merlot colorway) for another pair of socks and gave it to him as a Christmas present, with the promise that they would actually become socks.

The Carbon Twist socks are now about 75% complete – I am working on the foot and heading for the toe. I love the way this yarn knits up – it’s great for a pair of men’s socks. I knit the cuff for 6 inches on size US 1 needles (2.50 mm) and then went down to size US 0 (2.00 mm) for another 2 inches on the cuff , the heel flap and approximately half of the gusset before switching back to the larger needle. This produces a denser knit heel and should increase the wearbility of the socks. I intend to knit the toes on the smaller needles for the same reason.

For the Merlot colorway yarn, I am planning on doing the “Manly Aran” socks pattern from Antje Gillingham’s Knitting More Circles around Socks. This is a toe-up pattern and I am looking forward to trying this out using Magic Loop.

How to Knit a Helpful Swatch – Part 4 Swatching to Estimate Yardage NeededHow to Knit a Helpful Swatch – Part 4 Swatching to Estimate Yardage Needed

I have covered the basics of how to make a Gauge Swatch and calculate your stitch and row gauge in my previous three posts. Today’s topic will cover some basic math to help you estimate the yardage that you need using your yarn, your needles, and your gauge to make a sweater.

Let’s say you want to make a sweater using yarn from your stash and you need to know if you have enough to make it. To make this estimate, you need the measurements for the sweater you want to make. If you are using a pattern, the finished measurements should be stated within the pattern – ideally on a schematic. Some patterns may only state the desired measurements within the text of the pattern and you may have to read through to find them.  If you are making the sweater without using a pattern – you would use the measurements of the individual who will be wearing the sweater.

The image below shows a schematic for the back of a sweater of a drop sleeve sweater. The back is 28 inches long from the hem to the neck and it is 20 inches wide. Both the front and the back of this type of sweater are essentially rectangles. 

Schematic of Back/Front of Sweater

The schematic for the sleeves of this sweater are shown below.

Schematic of Sleeve

At this point, you have the numbers you need to calculate the number of square inches of fabric that you need to make for this sweater. For the front and back, multiply the length by the width on the schematic and then multiply that number by 2. Using the numbers from my example above:

20 * 28 = 560     560*2 = 1120  square inches for front and back.

The sleeve is a trapezoid shape. The formula for the area of a trapezoid is:

[(b1+b2) * h] / 2

Where b1 is the width at the bottom of the sleeve(8”) and b2 is the width at the top of the sleeve(15”) and h is the length of the sleeve(18”). Using the numbers from the sleeve schematic, the area for one sleeve is 207 square inches. Since you need two sleeves, you then need to multiply the area of the sleeve by two. (414 square inches)

Now, here’s a short cut – if you place your sleeves next to each other so that the tops of the sleeves are parallel – you have a parallelogram. To get the area of this parallelogram you simply multiple the width(15”+ 8” = 23”) by the length(18”). Try it – you’ll get the same number as above.

Add the square inches for the front and back to the square inches for the sleeves and you have the total number of square inches of fabric in the sweater. Now that you know the total number of square inches of fabric you need, you will need to use the yardage and weight information of the yarn you want to use to estimate how many skeins or balls of yarn your sweater requires. The yardage per weight of the yarn will be found on the yarn label – see image below:

You will use the yards per gram value in the estimate for total yardage. Now you need to knit a swatch. The swatch should be in the same stitch pattern that you plan to use for the body of your sweater. This swatch does not need to be the same size as your gauge swatch, but it should be wide enough and long enough to get an accurate weight, length and width measurement.  After you knit this swatch, you will measure its weight using a scale that measures to the nearest tenth (0.1) of a gram. Next measure the length and width of the swatch and multiply these values together. This gives you the number of square inches in your swatch. Now divide the number of grams by the number of square inches.(Do not round). You now know what 1 square inch of your yarn weighs. This is the number you need to calculate how much yardage you need for your sweater.

Example: My swatch measures 3.5 inches by 4.5 inches, which gives me 15.75 square inches. The swatch weighs 9.6 g. Dividing 9.6 by 15.76 gives me 0.622 g/square inch.

Here’s the final set of calculations:

Take the total number of square inches of fabric and multiply it by the number of grams per square inch. This gives you the total weight in grams for your sweater.

Total Number of Square Inches * grams/inch2  = Total grams of fabric

Total Grams/Square Inches = (1120 + 414) * 0.622 = 954.148 g

Now take the yards per gram value from the yarn label. (For example 218 yds/100grams). Divide the yds by the grams to get the number of yards in 1 gram of yarn.  (For example: 218yards/100grams = 2.18 yards per gram.)  Multiply the total number of grams of fabric by the number of yards per gram to get the total yardage for the sweater. Using the numbers from the examples above:

Yards per gram = 2.18 yds/g

Total Yards of Yarn = 954.148 * 2.18 = 2080 yds

To determine the number of skeins, balls or hanks of yarn you need: Divide the number of yards by the number of yards in the skein. Or divide the total number of grams by the number of grams of the skein.  Remember that you will want one extra skein for swatching. (In my example, I would need 9.5 skeins, so I would want 11 skeins with one extra for swatching)

What to do if you don’t have the yarn label

To determine how many yards of yarn you have when you do not have the yarn label or any information, simply measure out 10 yards of your yarn and weigh it. Divide the weight by 10 and you have the weight for 1 yard of yarn. Now weigh the skeins/hanks of yarn and multiply by the weight of 1 yard.  This will give you the number of yards for each skein/hank.

FO: Ruffle Scarf — Birthday Present for MILFO: Ruffle Scarf — Birthday Present for MIL

Ruffle Scarf I knit this scarf as a birthday present for my MIL. She wears scarves all the time and I thought she would enjoy this unique scarf. I knit this using a novelty yarn called “Sashay” by Red Heart Yarns. It’s a very interesting yarn to knit with. And Yes, it ruffles as you knit it up.

The pattern is really simple. You cast on 6 stitches and then just knit every row until you have used up the entire skein. It only takes one skein to make the scarf and when finished it is about 6 feet long.

My MIL was thrilled. She put the scarf on and wore it after she opened the bag. She exclaimed at how soft it was. She said she would be the envy of all the ladies in the independent living facility where she lives. (I made a BIG hit!) 🙂

Here’s the details:
Yarn: Sashay (Red Heart Boutique) Colorway: Hip Hop
Needles: U.S. 9 (5.5 mm)
Finished length = 72 inches Width = 3 inches

Notes about knitting with this yarn: See picture below of the yarn before knitted. This yarn is essentially a stripe of lace — with the bottom edge more finished than the top. The bottom is the finished edge of the ruffles. You knit this yarn using the top two strands of the upper edge of the lace. The yarn is quite slippery and it takes some getting used to — I used metal needles for this project and the combination of the slippery yarn and the slickness of the metal needles nearly drove me crazy! I recommend using a type of needle with some grab for this yarn — if I knit it again I will use bamboo needles. Also — it is not possible to weave in the ends on this yarn. When you are done, get out your sewing thread and a sewing needle — you will need to sew down the unfinished edges of the scarf to prevent the ends from raveling.
