Hard to say from the pic. Some look pretty large but sometimes it's just camera angle. Very pretty, metal that is enameled on would be my guess & that is what some jewelry is made of, so think that is right. Jan

Some pieces look like spoons (maybe plastic??)-either the bowl portion, or the handle portion. Otherwise, I can't quite tell. Very pretty, though!

And the centers look like buttons, which give you an idea of the scale of them.

I'm guessing it's spray-painted aluminum. I'm still busy making aluminum flowers, but haven't spray painted any, so this is JUST a guess.

In the roofing section, they have rolls of metal.
usually it comes in copper, 'silver', and a brown.
I think the brown would hold the spray paint best.
If you wanted to cut metal, I think that would be
the way to go.
Some of those look like metal to me.

I wrote a message to the person whose booth it is. And she said they are enameled metal brooches. I love the idea of using roofing metal to make flowers. I am just totally flower oriented lately. I noticed that HD has round metal switchplates. They might be good centers for metal flowers.
