Rebecca's project uses one hank of Blue Sky Alpaca Royal, which is not a cheap yarn it is an amazing yarn. It is what you want to cover yourself in. It is also perfect example of a yarn you can gift to the crocheter that has everything. They will LOVE crocheting with it and LOVE wearing it.
Rebecca and I go back a bit. She used to help crochet for me way back when, before she started designing. I knew she could knock out a project no problem that everyone would love to crochet. Speaking of loving to crochet, don't forget to check out her patterns for sale. She just started a new series of patterns based on storybook characters. You can see the first one, Classic Red, on her blog. Adorable, right?
