I have never thought of clear packing tape...hmmmm....I might have to try that! Does the punch go through it okay when cutting them out??
I use ET Lite & it is the best thing ever! Perfect every time! I use modge podge to seal my caps and haven't had a problem with ink running since. I also use the 3D Crystal Laquer when I just need to do a few caps for a special order.....it is awesome too! Good luck with your new ET Lite! Let us know
