If you decide to make shapes out of your toffee, be sure to push the cutters all the way to the bottom of the toffee. They will be stuck in the toffee until you break it up, so you either want to use a lot of cutters, or just make one or two and break the rest of the toffee into pieces after you cover it with chocolate and nuts. We had fun with this, but only had 3 cutters, so we just broke most of the toffee into irregular pieces. As you break the toffee up, you will find that you can loosen the cutters and the shape that you have made will be there once you remove the cutter. We kind of manipulated the cutters just a bit in order to loosen its grip on the toffee.
