I have a bunch of plastic storage containers, I think they were originally designed as storage for tackle. The compartments are perfect for my N scale rolling stock. BUT, I need to line each compartment with some type of foam padding, and I am having trouble finding a source for it. What I have found, was too thick (1/2") and I would like to find something more like 1/4" or even 1/8" in some cases. I would appreciate any help in locating a source.
