Scraps! I dig in my scrap piles and make almost all of my cards (except for multiples like Christmas cards) completely out of scraps. It's a great way to use up those little scraps and I'm a pack rat so I keep them all!
I love using prismacolors and gamsol! It's such a nice way to color stuff, and I love how it blends!
What is gamsol?
Gamsol is the name brand, but they are odorless mineral spirits.
First you color your image with your prismas, then you use a blending stump to pick up some Gamsol (I use a piece of felt to soak up some gamsol then just roll my stump on the felt), then start blending away! I love the way it looks!
Layering paper. I don't have any tips or special techniques BUT I do stamp the back of all my cards w/a flip flop stamp since I'm coo coo over flip flops. It's become by signature then I put my initials and date over the flip flop stamp.
