In the past, I would get these moldings ( like egg and dart ) made of some sort of composite material. We would steam them and apply them to a rabbeted area. We also used to get a extensive grape leaf arrangement and apply it to a valance of sorts. They could be made of a resin compound also. Does anybody know of the source for these and other architectural embellishment? I haven't released the secret adhesive yet, maybe its common knowledge. If you ask me I'll tell you though. When I was in the shops making cabinetry, they hand you stuff and you apply it. I should have keep track of the supplier, but didn't. Thanks
