Glass artists and crafters, this cutting mat is an absolute game-changer for your workspace! The 12x12 inch size gives you plenty of room for most stained glass projects, and the brilliant double-layer design features removable waffle grids that catch all those tiny glass shards and splinters. No more sweeping up dangerous little pieces from your table - just pull out the grid tray and dump them out. It's made from sturdy premium material that holds up to repeated scoring and cutting without wearing out. The grids keep your work surface safe and make cleanup an absolute breeze. Plus, it's versatile enough to use as a plant saucer or drip tray when you're not working on glass projects. Perfect for beginners learning stained glass techniques or experienced hobbyists who want a cleaner workspace. Installation is simple - just place it on your table and start working. The square grids do an amazing job containing the mess while you cut, and being able to remove the entire grid section makes cleaning so much easier than traditional mats. Such a smart solution that makes glass crafting safer and more organized!
