As it's getting nippy now, I'll be on the hunt soon for some jumpers, nothing fancy. Most of the knitwear I see is either 100% acrylic or a high % of it and in my experience, acrylic never lasts, it always goes bobbly, even after one wash.
There's quite a few jumpers/cardigans that I've seen before in New Look, Sainsbury's and Matalan, but the acrylic content puts me off buying!
