Here's my plexiglass cupcake tower that my Dad did last month. I used it to hold a 2-tier cake on the topmost plate, and 200 cupcakes on the rest of the plates. Top tier is 10" and the bottom tier is 34", if i'm not mistaken. We sort of followed the design of the big cupcake tree from cupcaketree.com, but in plexiglass. We also used a 4" pipe as the middle pole so I can put different decors depending on the theme (christmas balls, plastic fruits, flowers, pinecones, lights, etc). Everything is collapsable and i can use less tiers if needed.
Sorry for the mess. This was taken when the blue cover was still intact. We took them off, of course, so it's all clear. I am still waiting for the official wedding photographer to send me the photos -- I forgot my camera the day I delivered order. Tsk!
Thanks for looking!
