Here are some other ideas for birthday celebrations. I love those little boxes. Those are made using the Envelope die cut that you use with our Big Shot. You cut 4 envelopes and use the side flaps to connect them all together to create a box. The first one without the handle was called a cupcake holder. Can you see it each cupcake in a box. The other box with the handle has a cello bag with some chocolate in it. Now who wouldn't want a cute box with chocolate?
