What to do:
Simple. Lightly coat the heart stamp with acrylic paint and stamp the wooden circles. Once dry, glue the magnets on the back with the hot glue gun.
If you’ve never carved stamps before, and feel inspired to try, this would be a great first carving project. You’ll need a linoleum cutter and some sort of carving material. Heck, the heart shape is so simple and small, you could even use some sort of rubber eraser that is laying around the house. Using a pencil, draw the heart shape on a piece of paper. When you are happy with your shape, turn it face down onto the carving material and scrape/rub it with your fingernail. This will transfer your image onto the carving material. Use your linoleum cutter to carve away the negative space, and your wee heart will be complete.
I have sets of four magnets in a little stamped muslin bag listed in my shop for Valentine’s Day.
