Approximately 30 each. I get on to google and enlarge the No. 5 cake tin, height to be approx. 14" (I believe that's the height of the pan, place some baking paper over my computer screen and draw over, to make a template. assuming the size of each piece is 1x2x height I draw it on the paper and get my number of pieces. hope I haven't confused you.
You are close. thanks Kathy. I wonder whether there is cutter/embosser with the exact pattern though? I want only to emboss it and then paint, like you said. Failing which, I will enlarge and trace it and transfer on to the cake. will keep searching.
