Hide glue isn't "special" so much as it is traditional, but it's very friendly to reworking. However, you have to melt it and it's rather fragrant.
I've used pressure-sensitive felt from McMaster for a protractor case, seemed to work fine. Wally-world stuff probably had some sort of nasty adhesive on it. I think the McMaster felt was wool, but the stuff Gerstner sells is 100% acrylic.
