I am pretty new to crotchet and have made only a handful of items. I am working on a baby blanket. The number of stitches seemed correct in the foundation chain, except I think I crocheted way too tightly at the beginning. I have loosened my stitches on the last several rows, but I am not sure if this can be corrected. Do I need to start over or will this correct itself as I add looser rows? Just to confirm, does this seem to be due to having a few tight rows at the beginning? Thank you!
