I have a Samsonite briefcase that I use for my harp case. I'm looking to make a foam insert with cutouts for my harps. Does anyone have feedback on this layout or tips for cutting, materials, foam supplier, etc.?
I use Kaizen foam. Its a closed cell foam, like a pool noodle, so it doesn't hold moisture like a couch fusion foam does. You can cut it with a razor knife, but for best results, heat the blade over a candle or with a lighter. Then the knife cuts lt like its soft butter.
