Question: what is mb in knitting?
Answer: Note: MB = Make bobble: Knit into the front of the stitch, then the back, then the front, then the back, and then the front one last time, and slide the old stitch off — 5 sts in 1. Turn your work so that the WS is facing you (the stitches are on the LH needle). Purl the 5 sts.
