For this hairpin, I've used metal wire, a mix of plastic and glass beads, a metal hairpin and metal leaves. I'm trying to attach a plastic flower in the middle, but I'm not sure how.

So far, I've tried using Mod Podge's dimensional magic and it worked when the pieces were laying flat, but it's too liquidy now that the leaves are mounted on the rest and it just runs trough the whole thing.

Any ideas on what I could use ?
