Here's an easy card created with the masking and sponging techniques, I first masked off the moon with a circle cut from a sticky note then sponged on the lavender around the moon and then the purple. Stamped on the trees and witch and the panel is ready for assembly.
Tools:
Spellbinder oval dies and circle die for moon mask, Perfect Paper Crafting - Perfect Layers for cutting 1/8" borders, Martha Stewart border punch, Cuttlebug spider web embossing folder.
