I finished a ribbed scarf in K2, P2 with size 8's in caron simply soft. It looks cute but you can't see the ribbing because it pulls in-all you see is the K's. You have to actually stretch it to see the purls.
I've seen ribbing before on pro made items that looked like K2, P2 or K3, P3 and they lay flat where you can see the ribbing. How can I do this so it works for my next scarf?
