Cut a big circle from a piece of sturdy cardboard or tagboard. Mine was approximately 12"-14" in diameter. This will be the base of the cake.
Next, cut a rectangle from the same sturdy cardboard or tagboard and roll it into a cylinder. The open ends have diameters of about 2".
Cut a 2" in diameter circle from the tagboard and glue it on one end of the cylinder.
Using hot glue, place the cylinder in the middle of the round tagboard. I then cut out leaves from green tissue paper and pasted them around the around the tagboard.
Next, roll the diapers one by one and secure them with white elastic bands (or clear ones) to prevent them from opening up.
Place the diapers around the cylinder and secure with a thick elastic band. For this one-tiered cake, I used 18 diapers.
Make crepe paper roses. I made about four. Just cut a small portion from the crepe paper. Roll and twirl around to make roses.
Place the roses on the top of the cylinder (make sure to hide the cardboard) using hot glue. Use a pretty ribbon to cover the elastic band that holds all the diapers together.
Happy crafting!
