Spread the luck o' the Irish this St. Patrick's Day with a homemade shamrock stamp. Use it to decorate paper place mats, coasters, tablecloths, or anything else your little leprechauns wish to dress in green.
Press a heart-shaped cookie cutter (ours was 2 1/2 inches wide and long) into the cut face of a potato half.
With the cutter still in place, use a paring knife to cut the potato from around the heart (a parent's job).
Remove the cutter, then dip the heart into green acrylic paint and press it onto the paper. Repeat to make two more leaves, then use a paintbrush to add a swish for the stem.
