Large BG stamps are my passion! I don't own or use any DP at all, I make all my own. I love to just spend time in my studio, playing around with different layers. I've started keeping a file card file with samples of ones I've done that I like (I just glue a leftover scrap to the file card, with the details of how I did it on the back).
I struggled with using them effectively, though, until I bought my Mega Mount. That hunk of acrylic changed my life!
I've always got some stuff in my cart over at Impression Obsession, waiting for funds to come available.
