Hi, I'm a beginner knitter and need some help. I am knitting dishclothes with the breast cancer symbol. I've done the first 13 lines with no problem. The next series of lines start and end with B3. Eg: B3 K10 P4 K9 P4 K10 B3. I looked everywhere but can't figure out what the "b" stitch is. Thanks for your help.
