How To Make a 3 Tiered Cake Stand For Less Than $10 - I found cake stand hardware on ebay for cheaper than what the site has (she suggested etsy vendors). I like it mainly because it can be taken apart to save on room.
Clay Pot Cake Stand - you could take this in a lot of different directions! I'd use a food grade sealant on it. I have clear plexiglass cake circles that could sit under the cake without taking away from the look or putting the food directly on the paint.
