Do You Know? Swatching 101

This is the first in a series of  blog posts about swatching. It has taken me years to gain an appreciation for swatching and I frequently see posts in Ravelry forums about issues coming from swatches. If you are on Ravelry, you have probably seen them too. There are usually a number from new knitters/beginners that ask why the sweater they just knit according to a pattern doesn’t fit and many times, these knitters either didn’t swatch at all or didn’t knit a proper swatch. So, this set of posts is intended to share what I have learned over the years about swatching.

Take my quiz below to check your understanding of swatches.

Question 1: True or False: A swatch must be 4 inches by 4 inches (10 cm X 10 cm).

Question 2: True or False: The needle size stated in the pattern is the size needle you must use to obtain the pattern’s stitch and row gauge.

Question 3: True or False: Row Gauge is not important.

Question 4: True or False. Swatching is necessary for knitting sweaters and other fitted garments.

Question 5: True or False: You must get gauge when knitting from a pattern.

My next post will cover swatching to obtain gauge. If you have a question about swatching, please post it in the comments. I will try to incorporate an answer in my upcoming posts.

A Color Slip Stitch Pattern: Waffle CheckA Color Slip Stitch Pattern: Waffle Check

The cardigan for my GS was done using three-colors in a very easy slip stitch pattern, which I discovered is the “Waffle Check” pattern in Barbara G. Walker”s A Treasury of Knitting Patterns. It’s the Waffle Check Variation, which only has 4 rows. It creates a lovely nubby color pattern and is based on garter stitch – so it does not curl on the edges.

Waffle Check Slip Stitch Pattern

The pattern is done over an odd number of stitches – it is a 2 stitch, plus 1 pattern. Instructions are for knitting flat. This is the basic 4 row pattern:

With color A—
Row 1: Knit.
Row 2: Knit

With color B –
Row 3: K1, *sl 1 wyib, K1; rep from * .
Row 4: K1, * sl 1 wyif, K1; rep from *

To make the three-color pattern used in my GS’s cardigan – you alternate knitting rows 3 & 4 in two different colors. And the color changes could go on to many different colors if you wished – a good way to use up some leftover yarn, perhaps?

Now, I am currently working on knitting a hat to go with GS’s sweater using the Waffle Check pattern and the same colors. Because I am knitting this in the round, instead of flat, I have modified the above pattern as follows:

With color A—
Row 1: Knit.
Row 2: Purl

With color B –
Row 3: *K1, sl 1 wyib; rep from * .
Row 4: *P1, sl1 wyif; rep from *.

And because I don’t want two knit stitches together at the join, this is done over an even number of stitches. I’ll post the end result when I’m finished.

Part 1: Freeing Yourself from a Written Pattern or How to Use the Yarn of Your ChoicePart 1: Freeing Yourself from a Written Pattern or How to Use the Yarn of Your Choice

In my last post, I discussed the issues related to trying to substitute one yarn for another and suggested at the end of my post that if you want to use a yarn of a different weight & gauge than what the pattern calls for – you can design your own custom sweater using the pattern as a guide.
Today, I will focus on the first of two approaches for doing just that. WARNING – you must be prepared to take measurements, do a proper gauge swatch and get out your calculator. Yes, we will be doing some math…

Approach #1 – Use EZ’s Percentage System.

Elizabeth Zimmerman published her “unvented” percentage system for designing sweaters in the Knitting Workshop and gave us many examples of how to use it in her other books. EZ was always someone who dealt with knitting in a pragmatic fashion and basically cut through all the fluff and gave clear explanations of basic concepts. I encourage you to read all of her books – but if you want the complete explanation of her percentage system — Knitting Workshop is the source.

I am describing EZ’s Percentage System for two basic sweater designs – the yoke sweater and the Raglan sleeve sweater. Both are knitted in the round. You need to take some basic body measurements:

Width around the chest (Chest Measurement) [CM] The Chest Measurement is the “Key Measurement” (100%) and the starting point.
Body length to Underarm (Underarm Measurement)
Sleeve length to Underarm (Sleeve Length)
You must know your stitch gauge or Stitches per Inch [SPI]

The math follows:
CM X SPI = # stitches needed for the body of the sweater.

For a Yoke Sweater the basic percentages of the above are:
Body = 100%
Wrist = 20%
Upper Arm = 33%
Underarm = 8%
Circumference of Shoulders = 133%
Neck = 40%

For a Raglan-Sleeve Style Sweater the basic percentages are:
Body = 100%
Wrist = 20%
Upper Arm = 33%
Neck = 40%

To calculate – multiply the total number of body stitches by the percentage.

I think you get the idea. If you want to try using EZ’s percentage system, I recommend you either borrow EZ’s Knitting Workshop from your library or a friend or purchase it.

Here’s a link that will take you to Amazon.com: Knitting Workshop

I have also created an Excel Spreadsheet that will make the calculations for you. You can download it here: EPS_Calculator Spreadsheet.

Next post, I will outline another approach to sweater design.

Stitch Patterns – Three Examples of RibbingStitch Patterns – Three Examples of Ribbing

3Ribbings

All ribbing is a combination of knit and purl stitches across a row.  When you knit back on the next row, you knit the stitches as the face you, that is, knit the knit stitches and purl the purl stitches. The knit stitches form a ridge (or rib) and the purl stitches form a valley.  Ribbing is essentially a reversible fabric.  Ribbing is elastic crosswise and will stretch lengthwise and is most often used for sweater neckbands and bottoms and the cuff of socks.   Ribbing also “pulls in” naturally, so it will effect the shape of your garment.

One-By-One (1×1) Ribbing:

1x1Ribbing

This is knitted exactly as it says.  Knit 1 stitch, purl 1 stitch across the row.  (Remember to move your yarn from back to front as you knit and purl.)  If you are knitting this ribbing flat for a garment, you should be knitting an odd number of stitches, so that when the garment is seamed together the ribbing will appear to be continuous.   If you are knitting in the round, you should always have an even number of stitches.   This ribbing is the most elastic of ribbings.  It tends to look more loosely knit than stockinette stitch, and because it is so elastic, most patterns have you knit your ribbing on needles that are a size or two smaller than the body of the pattern.

Two-By-Two (2×2) Ribbing:

2x2Ribbing

This ribbing is made by K2, P2 across the row.  It is a multiple of 4 stitches, so when knitting a flat piece to be joined with another, you should be knitting a multiple of 4 plus 1 stitch so that the pieces will weave together correctly.  For knitting in the round, you would knit over a multiple of 4 stitches.  This is a popular ribbing and it works well for sock cuffs, but it is not as elastic as the 1×1 ribbing.

Three-By-One (3×1) Ribbing:

3x1Ribbing

This ribbing is also a multiple of 4 stitches:  K3, P1 across.  The rules for 2×2 ribbing also apply to this ribbing.  As you can see in the picture, this produces a wide rib with an almost invisible valley.  I have seen this ribbing used in sock patterns and it does give the socks and attractive looking cuff.

Other Ribbing Patterns: There are many other variations of ribbing, including Cabled Ribbing, Four-By-Two Ribbing, and Six-by-Three Ribbing.   I will include an example of Cabled Ribbing in a latter post on Cable Stitch Patterns.
