One of the best things about the iPad is that I can easily save images I see while surfing the net. The problem is that it doesn't save the source. So I am not sure where I found the inspiration for the sketch. Now I use pinterest to save cool stuff which does save the source info. I used Libby Pritchett's Pie Are Squared for my nephew in-law's birthday card. Birthday definition is from Hero Arts. Gears are from That Girl.
