Here’s a quick tip for how to arrange a stamp on a wavy banner so that it follows the curve of the banner:
Start by laying your die-cut banner down face down. The side you will be stamping on should be touching your craft mat or surface.
Next, place your acrylic block over your banner, and start placing your stamps on top of it, with the stamps upside down and backwards.
Keep arranging the stamps until you can see that they match the curve of the banner underneath.
When you have everything looking good, flip over your banner and your acrylic block. You can now stamp your sentiment and it should match your banner shape perfectly.
That’s all there is to it!
