At our quarterly in-person atc swap in October Annette did a demo showing embossing with an embossing folder onto hvac tape (the metal tape rolls you can get at hardware stores to use on duct work), painting with acrylic paint, and wiping off the high spots. She had supplies so everyone could try the technique and when we were done playing the challenge was issued to use our pieces in atcs and bring the atcs to the January swap. I had made 2 pieces of tape and these are the atcs I made with them. Lots of fun!!!
