Ripping out= uneven rows HELP!
I'm knitting the Juno Regina shawl and have come to a major problem in the body. I started to rip out to fix a stitch and now my rows are uneven. This shawl is knit in sections and they now have a sort of ladder effect to the middle of the shawl- each section is a couple rows longer than the one before. I have ripped back many rows and can't get it to even out. What can I do? Do I need to just use any stitch and knit in each section until it equals another? As soon as it's even, would I knit back so that I begin in the pattern again?
This shawl represents weeks of work already and I don't want to have to rip out the whole thing. Help!
