No matter how straight I cut a mat/layer for a card, I can't glue it down straight. Must be something wrong with my glue. :) I recently discovered Perfect Layers. They are awesome. I have the mini set, that is a great size to use on cards. I won't worry about scrapbooking right now, as I can glue those mats on straighter than cards.
You can find Perfect Layers HERE. It includes a video on how to use them.
The image on the card is a stamp by Close to My Heart (retired, I think)
Patterned paper is by Authentique.
Cardstock is from Stampin' Up
