I read somewhere here about a material that’s heavier than cardboard, but that can still be cut with scissors (I think??),

Until I can get my husband to make me some from wood, or buy the metal ones, does anyone know the name of this stuff ?? I want to be sure it’s not toxic ; kind of sensitive about that word right now

But I need something temporary to replace the destroyed plastic ones. And I’ve learned (too late for these) how to wrap them well so this stuff will last awhile, hopefully…
