Hi I went to Michael's today and their 1/5" foam core boards were $5.99!!!
Hobby Lobby didn't even have one thick enough!
I will be making a 4 tier square wedding cake, I will be stacking on location. What else could I use instead of foam core boards?? I know that I need the foam to use as support for the dowels going down the center and all but is there something else similiar to foam core I could use?
I'm a bit confused by your post, but this is what I do:
For each tier, I put it on a 3/16th" board the same size as the tier (i.e. a 14" square tier gets a 14" square 3/16th" board that I cut from a 20x30 sheet of foamcore.
I make a decorative board out of 1/2" foamcore that I cover with fondant, decorative paper covered with clear contact paper, decorative foil, etc. If the cake is very large, or very heavy, I might double the 1/2 inch board, but even so, 1 20x30 board should do. If you don't want to double the 1/2", sandwich it in between 2 pieces of 3/16th and you'd be fine. I decorate the edge with coordinating ribbon.
