A stitch called B

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. :shrug: :shrug: :shrug:

Is there a border?? I’m thinking that the ‘B3’ means to do the first 3 and last 3 stitches of every row in the border stitch pattern.

Oh, that makes total sense. There is a border which at the beginning is K3 pattern K3. Thank you so much. I never even thought of that. :cheering: :muah:
