Armholes ... too small (I think)

I am making a cardi for dd … no specific pattern I am using the knitters book of patterns as a guide line … but I think :shrug: that I have made the arm holes on the back piece too small … it is already finished and BO … and I am already 3/4 of the way through the left front. So my question is can I make the arm holes bigger??? :??

You could take out the bind off and knit the armholes longer. The only stitch that’s difficult to take out is the last one, but once that’s out the other stitches pop out.

You could also just seam it a bit differently. You’ll have to play around with the armhole decreases, but you could not seam the sides all the way up to the armholes and kind of seam them the best you can.
