All About Pocket Knives

I have a few wooden displays that are in need of some attention. The outside is in good shape, but the material in all 4 of them needs to be replaced.

Is there a material I should or shouldn't use? Also, I'm assuming just use fabric adhesive to attach it to the foam?

Thanks for any help that's given.

you can get velvet or a similar material at most craft stores like hobby lobby, michaels, or jo anns. depending on the fabric you choose a spray on or regular fabric adhesive should work fine
