Hi i would like to know how would i create the border using flute signboard if there isn't a suitable flat spot to glue it on?
As you can see from the photos the finished carbon product which i want to make a mould of, has edges that curve inwards, there isn't a nice smooth flat surface to mount the fluteboard.

would i have to fill in the curve section with yellow filleting wax then glue the board onto the wax??

Any help would be much appreciated

cheers
