I have uploaded a new video to my YouTube Channel. I made a post about Bee Stitch several years ago and it is one of my most viewed posts. Since it seems to be a subject that knitters search for, I have created a short video demonstration on how to do the “knit 1 below” technique and knit the Bee Stitch Pattern.
I have a written pattern available on the Bee Stitch in my Stitch Library as well. This pattern makes a lovely, fluffy scarf and works well for a hat when knit in the round. My “Bee Stitch Beret” pattern is available for download here or in my Ravelry designs: Beret in Bee Stitch.
Well, my Summer knitting project of a dozen dishcloths has now drifted into Fall. I completed Dishcloth #7 and #8 before Summer ended and then got busy with other projects and just left my needles and yarn waiting for me to come back and knit some more. So, I started Dishcloth # 9 on Sunday and finished it up today. Hopefully, I will finish the last three dishcloths before the end of the Fall season. Here are the completed projects:
Dishcloth #7 — Valentine Hearts
Pattern from Leisure Arts “Knitting Kitchen Brights Dishcloths” brochure. Yarn: Peaches & Cream Cotton, color Teal. This is a reverse stockinette stitch pattern on a stockinette stitch background that resembles a cut-out of hearts that I made when I was a child. It’s an easy knit pattern over 20 rows.
Dishcloth #8 — Zigzag Eyelet
Pattern from Leisure Arts “Knitting Kitchen Brights Dishcloths” brochure. Yarn: Lion Brand Kitchen Cotton, color Natural. Lovely little lace pattern done over a multiple of 11 stitches plus 2 and 12 rows.
Dishcloth #9 — Climbing Lattice
Pattern from Leisure Arts “Knitting Kitchen Brights Dishcloths” brochure. Yarn: Sugar’n Cream, color Cool Breeze Ombre. This is an interesting lace pattern that combines left twists with a four stitch eyelet pattern. I was getting tired of solid color yarns, so I went with this ombre — I really like the way it knitted up.
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.
Knitting Needles sizes are fairly straightforward in the sizes that one uses for DK, worsted weight and bulky yarns. (Size US 4 and up). But it is a much different story when it comes to small diameter needles used to knit fingering, lace and other finer weight yarns. This can be very confusing – I just discovered that there is a significant variation in the sizing labels for some of these needles.
Let’s start with the standard “US” sizing – which uses a numerical designation for knitting needles, from “0000” up to 35 – with the needle diameter increasing as the numerical designation increases. Seems like a fairly straightforward system – until you run across US size 1 & 2 needles that are different diameters. If you never use a knitting needle smaller than US size 4 (which has a diameter of 3.5 mm), this will not be a problem for you. IF, however, you get into knitting socks and lace using much smaller diameter needles – it may cause you to pull out your hair.
Fortunately, most knitting needles sold today also come with their diameter size stated as well as their US size. What I have currently in my assortment of circular knitting needles are as follows: US Size 0 (2.00 mm); US Size 1 (2.25 mm), US Size 1 (2.50 mm), US Size 2 (2.75 mm), US Size 2 (3.00 mm). These needles have all been purchased in the last 10 years. I have seen patterns referencing size 1.5 needles, so I am guessing that the size 2 (2.75 mm) needle may also be a 1.5, but it’s difficult to tell for certain. Just a word of caution to those using patterns calling for these US sizes of needles – make certain your metric diameter matches the pattern (if it’s stated) and BE SURE to check your gauge!
Point to remember: Gauge is the measurement of the number of stitches per inch you get with a particular needle – this is more important than using the size of needle stated in a pattern. Always do a swatch for gauge!
