re: brick embosser (stamp)

You mean hand?? Hee Hee…it’s rct’s. It was done for a cake collaboration.
I was also thinking. If you don’t want to push your stamp into the cake. You could roll out the fondant, press in the mat/stamp, let fondant harden a bit. Cut it in sections, then apply to your cake. That would also be another simple way to do it.
