Yep! That's 'flashing'. You can make so many things with it. You're only limited by your imagination! (I make wind chimes with it, roofs for bird feeders & birdhouses, cut out leaves & flowers to soder (spelling) onto trellises. It's unlimited!) Stuff can be your best friend in the grow room. I've made light switch plates from it, just to make them easier to find in very dim light.
