I have been working with the Clear Scraps 12x12 sheets a lot lately and I just love cutting them down to different sizes to use as cards or embellishments. Here are two simple cards using the 12x12 acrylic sheets.
I used my Purple Cows trimmer to cut the acrylic down and to get my wave edge.

Here I also used my Purple Cows trimmer to cut a 2.5x1.5 piece of acrylic to stamp on and use as an embellishment.
