I recently purchased a couple of collage sheets from "Dezinaworld" and have made quite a few cards with them. One sheet had a "purple" theme and the other was "autumnal tones". From each collage sheet I made about 5 cards - so that was 10 cards total!! Excellent value. And as I have sooooo much paper and embellishments I didn't need to buy anything else!
Here are a couple of cards I made from each sheet. The others I will add to my slideshow on my sidebar of my blog.
