Magnetic sheets: great for sticking thin metal dies to for storage.
Magnetic photo paper: terrible for sticking thin metal dies to for storage. They just aren't magnetic enough. They are barely magnetic enough to stick to the refridgerator.
However, I think they will do excellently for #FluidArt, whether that be #AcrylicPouring or #AlcoholInk, because they are basically plastic paper. So that's something new for me to try.
