As of June 2015, Simplify, Yarnspirations, Free Vintage Crochet, and Yellow, Pink and Sparkly have free online Santa crochet patterns. Simplify has instructions for a small Santa face at cakesbykristin.blogspot.com/2011/12/crochet-santa-face.html. Attaching a pin makes it wearable, but adding a loop turns it into an ornament.
Directions for a crocheted Santa gift tag are on the Yarnspirations website at yarnspirations.com/santa-gift-tag.html. Click on the Free Pattern button or Download tab. Both English and French instructions are available on the tab.
Free Vintage Crochet has a pattern for a Santa star ornament at freevintagecrochet.com/christmas/santa-claus-star.html. Santa's head, mittens and boots are the points of the star.
The Yellow, Pink and Sparkly site has a pattern for a sitting Santa at yellowpinkandsparkly.blogspot.com/2009/11/funky-santa.html. The decoration uses non-traditional colors, including pink, lilac and burgundy.
