I'm a rather big fan of carving pumpkins. I'm not entirely sure why this is, maybe it's because I get to roast the seeds afterwards. A few years ago I tried to find a Tux pumpkin stencil and came up dry, so I made my own. This year after many many hours of Gimping around (har har har), I have a THREE color stencil. Orange, lit up candle color, and sort of transparent orange. I created my artists rendition below. As you can see, I'm not a very good artist. The idea here is that the parts that look sort of like a cross between yellow and orange, are where one would just carve away some of the pumpkin, rather than cut it out completely. You end up with something a bit like this picture of a Gollum pumpkin I found (Note it is a three color carving)

My original stencil, along with the new one can both be found here:

When I finally get around to carving this in a pumpkin I shall post a picture of the finished product. I figured since I finished with my stencil early (I planned ahead due to how little art skill I have), there's no sense in not sharing this.
