Recently I wrote about the poncho that I made for my daughter for Christmas a couple of years ago. That same year I also made a Minecraft creeper hat for my son. My boys are absolutely in love with Minecraft, so I wanted to make something that was Minecraft themed. After some searching I found this great free crochet hat pattern on Ravelry!

This was my first, and only, time working in intarsia, so there was a bit of a learning curve going on here. But, the pattern was very straightforward and I really love the finished product. My son does too!
