Hi, can anyone help me with following instructions for a sleeve increase on an Erika Knight pattern. For some reason I just can’t seem to get it right! I have worked two knit rows and 1 row to set the sleeve increase as it states. I now have 23 stitches on the needle. It’s the following instructions I’m not understanding. I’m writing it exactly as it says:
Inc 1 st at each end of 3(3 3 3.6:6) foll 6th rows
then on 2(2 2 0:0) foll 8th rows. (29,31,33:37) sts.
I have highlighted the numbers i.m using for my size. (3, 2 and 33).
Any help would be greatly appreciated!
Thank you.
