I was wondering how in the devil do you cover a cake board in fondant?

I tried doing this with a normal plate this weekend, because there was no where to write on the cake (and I didn't have a cake board for this one), and it didn't turn out great The edges were cracking and the middle was puffing up. I did smear some bc on the edges, but it didn't work especially well. I may not have put enough. I ended up just cutting around the cake and pulling off the excess fondant. (its in the naughty cakes gallery, lol).
I know it would probably be easier with a board, but anyone got any tips or advice?

thanks in advance!

I lightly brush the board with water then apply the fondant exactly as if I were icing a cake

I usually just put a little piping gel on the board, lay on the fondant and smooth it out with a fondant smoother ( from the middle to the edges), to get out any air bubbles.

I use rose water brushed onto the board and then apply the fondant, brushing it smooth with the fondant tool or my hand. If you want to cover the side of the cake board as well, just sit your cake board on an elevated surface, smooth down the sides just like you would a regular cake, then cut off excess by running a knife around the edge.

I reuse my boards so I cover them with foil if I am applying fondant.

Make sure you press the edges, of the foil, in tightly against the board.

Roll your fondant to the desired thickness about a 1/4" to 1/2" larger than the board you want to cover.

Brush water onto the foil then place the fondant onto the board. Smooth the fondant.

I then use a sharp knife to trim the edges, flush with the edge of the board,taking care not to cut the foil.

I then usually apply ribbon to the edge of the board.

If you want to fold it underneath the board, just glue gun an extra board underneath, trimmed to be slightly smaller so that the fondant won't sit directly on the surface where the finished cake will sit. You need to insure your board is thicker than the fondant.

Thank you for all your replies! Sorry I haven't responded, for some reason its not telling me when people respond to this thread, its working for all the other ones and I have that little box checked

Squirrelly, I feel so dumb asking, but I don't fully understand about adding the second board ...where would I glue the extra board? The cake board I have right now isn't very thick, its the average foil covered board.

Ohhhh, now I get it!

Thank you for explaining it again!

Thank you to everyone else too, last time I didn't wet the entire plate, I just dabbed a tiny bit of buttercream near the edges.
