Worth a try, to avoid any sewing! The pattern I had wouldn't have worked that way, as each square had a different number of stitches and rows. they all ended up at 12"x12"
I hate sewing up knitting. I will look at this pattern and see what i can do. But for now, it's k1p1. And slowly, my diagonal grows. If I quit before I start the decreases, then I would have a triangular piece. I could call it a shawl!
