The back side is a big problem. It wasn´t a very good idea to use the same size needles for both the fair isle front, and the ribbed back, which is also knitted in a completely different yarn. I knew this from the start, while watching the backside grow and grow and get bigger and bigger compared to the front. But knitter’s denial is a powerful thing. “Surely this will fix itself after blocking!” Nope, it didn’t.
So a tiny note to self. Next time, frog! Rip it out before too much knitting has been done and it feels like an impossible task. Really!
