They look like a patchwork cutter or perhaps a very thin mold. Look to be made with either gumpaste or fondant or a combination of both.
a mold! I think you are right!! Thanks!
Yes, they are molded.......I can't remember now which one.. I think it's a Sugar Bouquets one which is out of business.
There may be someone who's made a duplicate mold, but the large rose was definitely an original Rosemary Watson silicone fondant mold ... I have one! I'm sure there are others on the market that are at least similar, if not exactly like it. Good luck!
