Where do you get a solid cake spacer.  I'm looking for a square spacer between 3 layers.  I've seen the spikes, and the balls and the posts but I would like to wrap rhinestones around a square.  Any great ideas?  PS if you couldn't tell I'm a novice!

ACheck your local cake supply store (not craft store) for cake dummies. If you don't have one, I know you can order online. I bought some from a company in Dallas, but I ordered through their website. I can't remember the name of the company, but I'm sure they would come up on Google.

You can use any styrofoam or a little box (filled with something to make it sturdy) or florist oasis. Just wrap said item in food-safe paper (e.g., butcher's paper, parchment paper, waxed paper) securely. Then apply the rhinestones to the covered square.

If you're near a craft store, such as Michael's, they wll probably have a section for styrofoam "blanks."

If you order on-line, Dick Blick has some that are less than 3 inches high:

AThank you both so much!
