This is a good post. Some of the items I have been using already. I found a pack of small dice recently @ Hobby Lobby in the doll house section. Noticed some 'coke' cans there recently. I use the jewelery pins with a formed circular ends with the crimp tubes and styrene tubing for 4 link systems. I bought some quilting quarter fabric recently to make upholstery. From an automotive supply group I bought some vinyl masking tape and used it for seat belt material. It is very flexible. I also use 4mm,6mm, & 9mm rings for gauge bezels. light rims etc. I made a couple of dome lights using them, filled it with clear nail polish after painting it blue. I've also obtained samples of wood veneer (attached to a flexible backing) for wood grain use. Keep looking, there's all kinds of goodies out there.
