I just worked with my flowers. I will post a picture later this afternoon, need to get the kids lunch!
I didn't use any of the spacers and used all the layers of petals. I put a dab of glue on each of the outer petals close to the base and that is enough to hold it in a cup shape, imo.
I put a 15mm rhinestone in the center and I think it looks great!
Ok, off to make lunch!
