-what stage would u cover the board after the entire cake is done or before
-what stage do i cover the rice krispies yellow part
ARKT body is a good idea!
I'd make it in 3 parts; 1)board 2)body 3)shell; I'd make, cover & detail each part before assembling
Cover the board a good week before you want to place anything on it, that helps you not to leave finger prints when placing the cake on top.
Make a card template for the body and build your RKT on top of that, you might need a dowl to keep the head up or you could use a styrofoam ball on a skewer- that would help you attach the eyes. Don't foget to build in a flat cake board to sit the shell on!
I usually cover RKT in melted white choc before fondant- makes it stronger
Good luck! hope you have fun making it!
