Hey Gang...........I'm a little late to the party, but just a little to add. I have used the cake bags and tips for crown moldings, corbels, ceilings, etc. I use the modelling paste in the art department at Hob Lob. When it is dry, it can be carved, sanded, etc. Yet you can "pipe" onto wal paper and it will be pliable when you lift it off. Cool stuff. This is an awesome way to side a house, and love that the drywall mud works as it would be cheaper! Oops, meant to say wax paper....it's not letting me go in and edit................
