Mentioning RH or WM can start a war here... I shudder to think what's gonna happen with both being mentioned in one post! :shock: I WORK at WM, and do most of my knitting and crocheting with RH, so I'll take the flak! :roflhard:
Seriously though, a soft acrylic usually tends to be a forgiving yarn, and nearly always is machine washable and dryable too. That's a definite concern in knitting for little ones. I find RHSS a little on the scratchy side, even after several washings. It does wear like iron though, and I would recommend it for a pullover or hoodie so it's not right up against the skin.
