Thanks all, for the nice comments.

Steve: Tandy Leather (I think their stores are called “The Leather Factory” or such) has some pig suede in a limited number of colors. I have some from them, and their hides are only about 7-8 sq ft. I also have some from Alma Leather in London, UK. They have a wide range of colors, and will ship here, though the hides are typically about 20 sq ft. Andrew Crawford (smartboxmaker.com) has begun offering 1/4, 1/2, and whole hides in two or three colors as well, making the larger hides available at a reasonable price. Those are my three best sources.
