It's quite simple to do and goes rather quickly. All you need is some lightweight cardboard (like a cereal box) or scraps of cardstock would work great, too. At first I tried to line the holes up perfectly, but then I decided it didn't matter. What I was really looking for was the texture.
I even punched and cut some funky letters and numbers. Who knows where else this might go? You can see in this (badly taken) photo, that it worked great. I pressed the home made "sequin waste" into wet gesso so it would leave an impression. A few thin layers of acrylic paint and a couple dry washes later, here's the texture I was looking for.
So get out your hole punch and see what your creative muse will do with it, and let me know if you come up with more ideas for creative hole punching!
