If you don't have it yet, go get it! This has so many possibilites it is amazing! You can make this into a 4x6 mini album or do like I did and just use it as some of the pages in a 6x6 album. It is 12x12 so you can put lace cardstock on it and create your layout directly on the overlay. It is heavy enough that it is easy to work with, but you can cut it with your trimmer easily. Just remember to take both sides of the protective backing off. I forgot and my edges were not straight on one of my cuts. Other than that, have fun!

This clear acrylic sheet made by Hambly works real well in your Sizzix machines. I used it to cut letter tags for my project and it cuts great with the Sizzix Big Shot. I also cut a title piece with my Carl cutter and put some sticky bling embellies on it and they stuck on it great. Wonderful little product for all your clear inspitations. Make sure you remove the protective film from both sides.

I bought two sheets of these and cut them (using scissors) into "shell" shapes for a mini-album i was making. The overlays were easy enough to cut through and punch holes, but yet sturdy to act as clear "pages". I would highly recommend these to anyone who needs anything "clear".
