Is there any way to keep the St st from curling up? Or to uncurl it the work? I have a little ways to go before it really matters, but I would like to know. :??
St st will always curl by itself. If you added a border such as ribbing, seed stitch or similar then this will help prevent curling.
Blocking may also help eliminate or cut down curling.
