I recently picked up a set of square dies for my Sizzix Big Shot that were labeled as lace edged, but looked to me like postage stamps. I used one of the sizes to as the base for a couple of earring display cards.
Then I cut one black and one white square of paper using a guillotine and ran them through the Sizzix in a wood grain embossing folder. Glued them to the bases and punched a couple holes in them.
