Knit1pug2’s recipe for puffs:
Using a long tail cast-on, cast-on 20 stitches, alternating between back and front needles. You will have 10 stitches on each needle. Turn work and begin knitting into the last stitch you cast on. This will give you a nice ridge on the bottom edge. Continue to knit around all 20 stitches. You now have knit 1 plain row.
Row 1: K1, yo, knit to last stitch, yo, K1 on each needle
( yo’s increases instead of the kfb called for in the pattern)
Row 2: K1, knit into back of yo, knit to next yo, knit into back of yo, K1 on each needle
Continue repeating Rows 1 & 2 until you have 20 stitches on each needle.
Follow the pattern for the decreases omitting the final K row.
Bind off in purl to match the cast on ridge. Don’t forget to follow the bind-off instructions in the pattern about the final 4 stitches, just purl them instead of knit.
