We were so excited to see a wool-free sock yarn that had good stretch and nice colours we had to get it. It's going for a sparkly, christmassy sort of theme, but the basic yarn knits up to a stretchy, bouncy fabric you wouldn't expect from being 100% synethetic. Comes with a free pattern for socks, it will also make lovely accessories. The sock pattern uses 3.75mm needles which seems a little odd - all but the larger sizes of the knee high design take a single ball.
