Here is an idea. If you were going to enlarge it enough it wouldn't be a big issue to cut out all the different shapes of fur for each seperate color. Break it down into different shapes for different colors ie:shades of browns, whites & markings on his belly as seperate pieces. I'm not suggesting that you put a layer of fur over a layer of fur, but instead for example, on the white tummy you could cut the whole shape of the tummy out of white & then mark on the back side of the tummy where the 7 spots need to be & then cut the white spots out to make room for the brown ones you'll put in there instead. You could applique them all onto a background piece that has the drawing transferred onto it. Start basting on pieces like a puzzle & then just watch it grow. Sounds like a fun project & hope you share your results with us!
