re: How to make the grooves on the top of a record cake

To make the grooves you can use a decorator comb, as for the stack
of records couldn’t you slice the cake thinly; cover in sugarpaste
do the grooves ( along with any other details ) and stack them on each
other- or maybe put them in a box shaped cake like they were just
taken out of the attic or something lol! Hope this helps xx
