I'm planning on decorating a small chocolate-covered sheet cake (about 8x10 inches) with this design, at the request of a friend...
I was hoping to achieve this by making lots of 1/4 inch square tiles from different coloured modelling chocolate (X-Acto knife + quilting rule!). I'm a bit apprehensive as 1/4 inch will make for very fiddly squares that won't withstand much handling. Has anyone got any advice/experience in this mosaic-like technique using MC from Wilton candy melts? I've some experience with MC, but only using large pieces.
Also, the pieces will be placed on a smooth top surface of dark chocolate. Any tips for how to 'glue' them? I'd rather not use melted chocolate as it's a pain to keep liquid. Would a light coat of veg shortening work, do you think? Or corn syrup diluted with water?
All help gratefully received!
