Buying Wedding Cake Supplies

Michael's Craft store and A C Moore have great deals.

Price is pretty subjective--what is cheap to one can be expensive to another. I used to do cakes, and often people were shocked at the extra "charge" for the toppers or specific material they wanted on their cakes. I let them price some items they wanted, and then they realized that I did not mark that stuff up. Things like fountains and bridges could be really expensive to buy and often came back broken, so I had them pay deposits and sign leases that if they broke them, there would be additional charges. I always bought my supplies from the Wilton Cake Company, since they had the best and most diversified items. Usually people who want a traditional cake topper, want to keep it and don't complain about the price too much.

What about styrofoam rounds and spackle, thinned with water (to frosting consistency)and tinted (?)

Any party supply place has them inexpensively and also Walmart has a section with all wedding items. Good luck!
