I felt like I wanted mine to be special, so I decided to sew it myself. I went to the fabric store and bought the tackiest warmest faux-furs they had.
I had never sewn anythign before, and I was amazed by how much frickin work it was. Each step took about an hour and there were like 25 steps.
I made it from a 'simple' pattern, even a simple pattern takes multiple days!
