HI there, I am knitting for the first time a raglan pullover for my son. I followed the instructions to the tee. My problem is that the neck is too small my for son to pull down his head. I removed few rows but it is still tight. Now i have come down to the row where i did the first BO of the stitches.The next row would be to decrease the raglan decrease to widen the neck circle. IS there a way around this problem.
