Let me introduce you to this week's free crochet pattern, the Ribbed Skater Beanie.
This pattern is worked from side-to-side in back loops only, to form the mock ribbing. Use a slip stitch join to seam the first and last rows. Each beanie took me about 75 minutes.
I used a size 4 weight yarn, Impeccable Tweed. I'm really loving this yarn. I've already made 4 patterns with it and I'm going to need to get some more soon.
