About the yarn:
Special DK
Stylecraft's Special yarns are class leaders, arguably the best 100% premium acrylic yarn on the market with a huge number of colours to choose from. This yarn has a super soft handle, is naturally anti pilling and tough enough to handle being thrown in the washing machine. The Special range includes 4-ply, DK, Aran, Chunky, XL and Baby qualities in a fabulous range of colours to meet every knitter (and crocheters) needs.
 
You will need: 5mm (UK 6, US H/8) crochet hook.
