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.

Part 2: Freeing Yourself from a Pattern – Step 1, Take Good MeasurementsPart 2: Freeing Yourself from a Pattern – Step 1, Take Good Measurements

In my last post, I outlined how to use EZ’s Percentage System to design a sweater. Today, I will spend some time answering a question from Amanda, who asked, “What do you do when the pattern does not have instructions for YOUR size?”

This is very frustrating for those of us who are either smaller or larger than the range of sizes given by the pattern designer. I have never fully understood why some designer’s only develop their patterns for “Small, Medium, & Large”, though the trend seems to be to at least go up to “Extra Large” in current knitting publications. But, if your measurements do not correspond to the designer’s definition of “medium”, you may still find yourself with a sweater that is not well-fitting.

Isn’t that the goal for all of us? To knit a well-fitting garment? So, once again, the answer is to use the pattern as a general guideline and develop your own sweater according to your own measurements. Your measurements are your starting point.

There are two ways to take your measurements:
#1: Take measurements from a sweater that fits you the way you like/love.
Lay the sweater out flat on a table or other flat surface and take the following measurements:

The Chest Measurement [CM] – this is the widest point of the sweater, usually right below the underarm. Measure from side seam to side seam. Remember that since you are measuring with the garment laying flat, that the actual chest measurement is twice this amount. (Important if you will be knitting in the round).

Shoulder Width[ShW] – this is the measurement across the shoulders from the seams or the point where the arm meets the body. This measurement is important for a proper fitting sweater.

The Neck Measurment [NM] – measure this for both the front and the back and note if the garment has shaping that creates depth – due to a difference in the front neckline from the back.

Armhole Depth [AD] – measure from the top of the sleeve at the shoulder seam down to the underarm.

Sleeve Length [SL] – measure from the top of the sleeve at the shoulder seam to the beginning of the sleeve.

Wrist Measurement [WM] – measure the width of the wrist at the bottom of the sleeve.

Sleeve Width [SW] – measure the widest part of the sleeve.

Side Seam Length [SSL] – measure from the bottom of the sweater to the point where the sleeve meets the body at the underarm.

Back Length [BL] – at the center of the back – measure from the center of the back neck edge to the bottom of the sweater.

Front Length [FL] – at the center of the front (or front edge if a cardigan) – measure from the front neck edge to the bottom of the sweater.

Other measurements that you may want –
width of sleeve at the elbow
width at waist (if sweater tapers in at the waist)

I am including a diagram that you can use to record these measurements – click here: Measurements Diagram.

#2 – Take your measurements using your body.
Note – this is best accomplished with the help of a good friend. Measurements to be taken are the same as above, only taken directly from your body. You will need to figure in “ease” when calculating your pattern changes.

Now a few words about “Ease”. Ease is an extra amount of fabric that provides a garment with movement and shaping. When you take your measurements from your sweater – they will include the ease of that sweater. When you take actual body measurements, you will need to add in an appropriate amount of ease.

Close fitting garments have less ease and in some cases have negative ease, while loose fitting garments may have a significant amount of ease. Generally, the guidelines are that a classic fit has 7-10% ease, a close-fit will have a negative 7-10% ease and a very loose fit may have up to 20% ease.

So, now you have all the measurements you need. Take a look at the pattern you are wanting to use – hopefully, there is a diagram in the pattern that gives the finished measurements for each size. If not, you may want to use my diagram to write them down. Make note of the differences between your measurements and those in the pattern.

Also, make note of any textured stitch patterns or colorwork patterns used in the pattern. You need to know what the base number of stitches is for the pattern repeats. This is usually something like: “7 stitches over 9 rows” or “7 stitches, plus 1 over 9 rows”. Write this down – you will need it later.

That’s enough for today. Next post: Step 2 – Analyze the pattern.

Finished SocksFinished Socks

Knitted striped socks

Knitted striped socks


I finished my striped socks yesterday morning. I am pleased with how they turned out. I used a self-striping yarn from Patons Yarns and it was fascinating to see the stripes evolve as the socks knit up.

I did not really use a pattern for these socks. There are literally thousands of free sock patterns available on the internet, but you really don’t need them if you understand the basics of knitting socks. I started with a gauge swatch and used my foot measurements to determine the number of stitches I needed. The “how to” of this seems to be enough for a separate post, so I will place that in my queue for future topics.

I choose to do a picot hem at the top of the cuff, a 3 by 1 rib for the cuff and instep, a slipped stitched heel flap with a square heel turn. My mentors for these socks were Nancy Bush – I consulted her book “Knitting on the Road” for advice on the square heel and Cat Bordhi, whose book “Socks Soar on Two Circular Needles” contains a wealth of information on how to knit socks.

Knitting socks on two circular needles

Knitting socks on two circular needles

I used the two socks on two circular needles for this pair of socks. I prefer to knit socks two at a time, because when you’ve finished, you have a pair of socks and don’t have to go back and knit that second sock. You can knit socks two at a time using either two circulars – as shown here in my photo – Or you can use the magic loop technique. I started another pair of socks last night using this technique – so I’ll post about them later.

The Roomba Ate My Socks!The Roomba Ate My Socks!

Roomba
I have a Roomba – which is a small robotic vacuum cleaner. You are supposed to be able to contain it to a single room using little devices called “lighthouses”. I really like this little guy for frequent vacuuming of my kitchen. So, the other day, I turned it on and left it to run around the kitchen while I did some things in my office.

Well, it escaped the kitchen and headed off into the living room – where my two at a time socks using magic loop project was laying beside my recliner (I’d left them there the night before) …AND…the Roomba ate my socks!

I heard this weird little sound coming from the living room and went to investigate – and there I found the Roomba thrashing about entangled in my 40” circular needle and the yarn from one of the socks. (I was so traumatized that I forgot to take a picture.)

After turning the Roomba off, it took me several minutes to remove the yarn from around the various moving parts and then deal with the fact that the circular needle had somehow ended up wrapped around one of the wheels. Eventually, I succeeded in extricating my circular needle – but it was a close call, as I had begun to consider the possibility of having to cut the cable. (WHEW!) Fortunately – one sock was still on the circular needle. The other, however, was laying in the middle of the floor – off the needle and minus its ball of yarn. I tenderly picked up this wounded creature and set it aside to recover from all the trauma.

I discovered that the lighthouse that should have prevented Roomba from going into the living room wasn’t working (dead batteries). Once I replaced the batteries, the darn little thing worked just fine and stayed in the kitchen where I wanted it to be.

Socks_BackTog
Happy News! – I was able to frog the wounded sock back to a point that I knew where I was in the pattern and then pick up the stitches and reconnect the yarn to the sock as I reknit it back to where it had been before it was attacked by the Roomba. It is now back on the same circular needle with its brother.
