Called my local Tandy Leather shop and they only sell leather belts in the 3in. width - the TK belt is 3.75in. They also said that they don't sell white leather and that dying it - generally speaking - gives ok results and that it cracks.
Any suggestions on where to find this or alternatives? I also currently have a 3in. wide strip of white elastic material that I thought about using, but I'd prefer leather.
