How exactly are you supposed to do a swatch?

Do you do the # of stitches and rows that the pattern gives for the guage? or do you do extra? I haven’t really bothered with them so far, but I want this project to be good so I need to do it.

Heres how I do mine:

If the gauge is 22 stitches in 4 inches, I cast on 28 sts, and knit the first and last 3 in garter stitch. It makes the 22 center stitches (in stockingette) easier to see and measure. I do the same for the top and bottom.

Swatch Out! :thumbsup:
