Swatching for Success!

It has been a while! I could blame the unrelenting heat: high 90’s with 98% humidity for my lack of activity, but  this kind of weather provides great opportunities for hibernating with the air conditioning and getting lots of work done inside. The truth is that I have been busy prepping for my two classes at FIT (Fashion Institute of Technology) in NYC this fall and also a trip to Denver with those great folks at Craftsy.com in early fall. Just saying…

Before I get into this week’s topic, I also want to mention that I will be doing a class here in Northford, CT November 12 & 13 for the North Branford Recreation Department and will post the contact and registration information in a couple of weeks. If you live in the Northeast – save the date!

Swatching

One of the most important – and least addressed (and maybe one of the most boring)- parts of knitting is The Swatch. I sometimes spend an afternoon swatching a variety of yarns, then another day charting and planning before I actually get around to any knitting.

The most important thing about swatching is to make sure you knit enough stitches and rows to accurately measure – this is no place for skimping! If you use a charting attachment (i.e. Knit contour/radar/leader), you must do your swatch according to the directions in your manual. These are the normal guidelines:

Standard gauge machines           40 stitches/60 rows

Mid-gauge Machines                  30 stitches/40 rows

Bulky machines                           20 stitches/30 rows

 

Programs like Garment Designer and Design-A-Knit can utilize these same measurements or the number of stitches/rows in 10 centimeters. If you are just trying to match somebody else’s gauge or designing your own patterns, it really doesn’t matter how many stitches and rows you knit as long as you write it down so you can figure out the exact gauge later on.

Assume that I am swatching a yarn for my mid-gauge machine, I’ll cast on with scrap yarn over a width of 40 stitches and knit some rows. Next, I’ll change to my main yarn and set the row counter (RC) to 000; knit 20 rows and then make two eyelets by moving the 16th stitch at each side of zero to the adjacent needle, leaving the empty needles in working position (WP). Knit 20 more rows and then knit two rows with waste yarn.

The scrap yarn acts as a marker for the required 40 rows and there are 30 stitches between the two eyelets. Now, so I don’t forget what stitch size I used, I make a series of eyelets in the scrap yarn. For size 6, I would just make 6 eyelets, but for size 6ŸŸ I would make 6 eyelets at one side and two more at the other. Follow the eyelets with a couple more rows of scrap, slowly increasing (or decreasing) the stitch size for the next sample.

Then just repeat knitting 20 rows, making the eyelets to mark the 30 stitches and knitting 20 more rows. Follow that with some rows of waste knitting and eyelets to mark the stitch size. I often knit a strip of gauge swatches with four or five different sections so I can compare and choose the absolute best gauge.

I bind off the strip and then finish it exactly as I plan to finish my sweater. For most yarns, that means hand wash and lay flat to dry. For superwash wools or cottons, that means running the swatch through the dryer.

You don’t want to measure any swatch until it has been finished. Otherwise, you might be wasting your time knitting a sweater that only fits until the first time it is washed. Most yarns have some tendency to bloom (i.e. fluff out) or shrink or otherwise alter once washed and you don’t want any surprises later on!

Lay the swatch flat and measure between the eyelets for the stitch width and between the top and bottom rows of waste knitting for the rows. You’ve already done the counting!

For a charting attachment, you need to use the special ruler that came with your machine. It converts the required number of stitches/rows to a single number you can use to choose the stitch scale or set the row rotation. For other purposes, you can just divide the total number of stitches (or rows) by the inch measurement to find out how many stitches (rows) per inch.

For general purposes, I usually make a chart like the one below to record the measurements of 30 stitches or 40 rows so I have all my figures in one place to compare and choose which stitch size will get me closest to my gauge goal.

Stitch Size Tagged 30 stitches 40 rows
6
6Ÿ.
6ŸŸ..
7
7Ÿ.

If you are trying to match a specific gauge and haven’t done so, I plan to address some charting in the next couple of blogs so stay tuned!
