I think that would be a good pattern to use Soft & Stable on (or the new In-R-Foam). Also you might want to add a flap at the other end that would cover up the pockets so things don't fall out. I have a paintbrush holder like that - it's got the regular pockets along one long side and a large flap along the other. In order to fill the pockets, you'd lift up the flap, fill the pockets, lay the flap back down, then roll up the whole thing and secure w/velcro.
