I’m ready to start the sleeves of my cardigan! I’m perplexed by the instructions:
Slip 45 sts from waste yarn to larger needle. Join yarn at center of stitches cast-on for underarm, pick up and knit 5 sts, work in ribbing as established across 45 sts previously on waste yarn, then pick up and knit 4 sts in remaining cast-on stitches.
So I slip the stitches from the waste yarn back onto my needle. Then do I pick up and knit 5 stitches ? Or do I start in the middle of the row ("join yarn at center of stitches)? If I start in the middle, do I knit until I get to the middle, then pick up and knit 5 new stitches? What does it mean here to join yarn at the center of the cast-on stitches?
