I am making a sweater FLAT on circular needles. I casted on 190 sts and began knitting. To my horror, when I reached what should have been the end of my stitches, I discovered that I had unintentionally joined the stitches in the round (there is a strand about two inches connecting the beginning stitch from the last stitch). How do I unjoin them? Without frogging!!! Please tell me I can do this without frogging. It took forever to cast on these stitches. Thanks.
P.S. I hope the included pics are clear. I’m trying to show that the sections are connected by the lead yarn, not the tail. Tiny thread on giant needles is intentional to make frill per the pattern.
Here are the pics
