Saw this on Pinterest the other day and had to give it a try. Started off with plain white cardstock and waxed paper. Added some collage bits and several layers of mod podge.
After it dried I ran it through the Big Shot with some different embossing folders and did some sanding to distress them.
Next I did some inking and more sanding. Inking and sanding, about 4 or 5 times for each one.
I added more embellishments and mounted the one with the musical theme to another piece of cardstock.
Really, a fun technique and I'll definitely be doing it again!
