Hey, can I jump in here? I taught my friend how to knit and purl, and told her about stockinette curling, so she is doing her first scarf in 4x4 rib. I haven't seen it in person, but she says that it is curling. Does 4x4 rib curl badly? She's about 6" into the scarf, and since it's her first, I don't want her to be discouraged with something unwearable.
