Hi. I just finished a crochet scarf with Vanna's Choice yarn, which is 100 % acrylic. When I lay it out flat, it looks even. But when I try it on, it bows in a tiny bit towards the chain edge (even though I tried to crochet really, really loosely). I was wondering if blocking would help and, more importantly, whether blocking works with acrylic. I've blocked acrylic blends before and have been pleased with the results. I usually just wet the item, gently blot the water out with a towel, and then lay it out to dry. This is a gift so I want it to be perfect. Any advice would be appreciated!!
