The Spearmint Mittens knitting pattern is my newest pattern and it cals for one skein of malabrigo yarns caracol and one skein of malabrigo yarns chunky.  This pattern comes with a link to my YouTube tutorial for a full walkthrough on how to complete the gussett thumb.  I also have 12 kit options in stock in the shop and each kit come with a free copy of the knitting pattern
