There are side vents in this pattern. After knitting the back and shaping the shoulders the pattern says, "Side Vents, With larger needles and RS facing, pick up 9 sts along long edge of side vent. Work even in garter st for 5 rows. Bind off loosely and do the same to other side."
Looking at the picture on the front of the pattern, I'm not understanding what the long edge and the short edge is, and why I'm supposed to knit these "tabs." Can I skip that part?
