This mini class introduces you to increases. Learn how to knit front and back and how to make one (bar increase).
There is some homework. You will need to bring 2 swatches in worsted weight wool and size 8 needles. For the swatches, cast on 24 stitches and knit in stockinette (knit the front, purl the back) for about 2 inches. Put the live stitches of one swatch onto a stitch holder, but you can leave the second on one the needles.
