Kristen Laflamne here. My second boyfriend ever, way back when I was entering college, worked summers at a sail-making shop. One day he came over with a gift he had made from scraps lying around.
Using the protective cloth for sail covers, a big grommet, some leather, and the industrial sewing machine, he made me a roll for my paintbrushes that could handle the wet mess of an art studio yet breath enough that my brushes wouldn't mold if I put them away damp.
That was at least 25 years ago and I still use it today! All my brushes live in this roll, and I pull it out of the closet every time I sit down to paint. It's incredibly sturdy and hardly shows any wear. That's a gift any artist could love.
