I had a wood board laying around in the garage. It was the perfect size and sturdiness for a large diaper cake. I used the wrapping paper that is incorporated with the baby shower theme to wrap the board.
STEP 1: I used the curling ribbon to create a circle with a 12" diameter. I started to fill the circle with diapers in a circular pattern.
I'm not fond of the rolled diaper cakes. It seems much more tedious to roll diapers individually. I cannot even imagine what the new mother thinks when she has to undo each one.
STEP 2: Once I was almost done filling in the first layer, I placed the cardboard tube into the center of the diaper cake.
STEP 3: Repeat STEP 1 with a smaller circle of curling ribbon. FILL! FILL! FILL!
Repeat STEP 1 for each tier that you want to create. I was happy with four tiers and I reached the top of my cardboard tube.
STEP 4: I wrapped each tier with 3" white ribbon and 2" and 2 1/2" colored ribbon. I used a safety pin to keep the ribbons in place without pinning them to the diapers.
STEP 5: Decorate! I had the yellow daffodils on hand and just created some bows. I created small clusters of daffodils and tucked them into the existing safety pins. I pinned the bows to the ribbons to hide the existing safety pins. I did not secure the diaper cake topper because I knew that it would not move around a lot.
