Hi Gloria2005! Sometimes local churches or even elementary schools or colleges and even a friend who has a refrigerator large enough for the sheet cake and would not mind if you can either rent a space or simply just use it for the occasion. I had to do a sheet for a graduation event and what I did was that I put in the top part of refrigerator and the other part in second shelve of refrigerator and day of the event fill and frost and decorate it. The other items in frige, I put them in a large cooler or freezer only until the cake was done and ready to go. I then put items back into frige and out of freezer back to frige.
