That's what I wanted to know.

Turns out it can be a centerpiece for baby showers. Yes, it's an actual cake, but people don't really eat it (thank goodness). It also doubles as a nice gift for a new baby.

Here's what you need to make one:

• Approximately 50 medium size disposable diapers. The number depends on the brand and the individual sizes
• A large platter on which to build the cake. A 16" party platter works fine
• About 70 feet of narrow ribbon for tying the rolled diapers (1 ft. per diaper) and tying the tiers
• Approximately 8 feet of 1" wide ribbon for finishing the tiers
• One tall baby bottle
• Small candies to put in the baby bottle
• Tape
• Various baby items such as pacifiers, teething rings, combs, brushes, rattles, bibs, and so on

Step 1 - Set up the diapers

• Cut 48 feet of the narrow ribbon into one-foot lengths.
• Decide whether you want the printed decoration on the diaper to show on the cake. If you do, roll each diaper from the fold outwards, keeping the decoration on the outside. If not, roll with the decoration on the inside.
• Tie each rolled diaper with a length of narrow ribbon.

Step 2 - Assemble the tiers

• Fill the baby bottle with the purchased candy. Stand five or six diapers around the bottle and tie them tightly around the bottle with a length of narrow ribbon.
• Create the second tier with approximately 15 diapers. Once again, tie tightly together with the narrow ribbon.
• Create the third, and largest tier using approximately 27 diapers. To make the tying simpler, first tie an inner circle of diapers together. Then stand the final row of diapers around this circle and tie once again.

Step 3 - Finish the cake!

• Place the largest cake tier on the platter. Using several pieces of adhesive tape on the underside of the diapers, tack them to the platter. Don't use so much tape that the diapers will tear when the mother disassembles it.
• Place the second tier on top of the base and attach with tape to the lower tier.
• Place the smallest tier on top and attach as you did the other tiers.
• Tuck the various baby accessories inside the ribbon, all around the cake. Make sure they fit snugly, and tie with more ribbon if necessary to keep them from falling off.
• Finish the cake with the one-inch ribbon wrapped around each tier to help secure the accessories and provide a finishing touch.
