I have used the stamp set High Tide from Stampin' Up!® to use the Retaform Technique sometimes also called the Grid Technique for this sympathy card. I really enjoy using this technique using different stamp sets and different layouts. It's such a WOW factor to your card and you just never know how the effect will be until you have finished.
