One more technique for Messy Technique Week - Clear Block Wash.
This is a fun way to make clear blocks onto background stamps.
Simply color markers onto the clear block, spritz with water and place onto Whisper White paper. Let it sit for a bit so the colors will run together. When you lift off the block you'll have a pretty, blended together background.
HINT: Use a magazine, newspaper, or stamping mat under Whisper White to add a little "give" - clear blocks stamp better with something under them.
