Where to buy these flower centers
 

I am looking for the type of centers that are in some Prima and Recollections flowers. (NOT stamens) They are round and bumpy, and supposedly made of "foam", but they are hard, not squishy. I have a link so that you can see what I mean: Flower centers. All of the flowers but the one way on the right have the centers I am talking about. The little round bumpy thing in the middle. I am looking for a craft store online that sells those centers separately. I have seen stamens made in that fashion, but they are like long, not the little round buttons like in these flowers. It also does not help that i do not know the proper name for them. I have googled "foam flowers centers", "round flower centers", and several other combinations. No luck. They must sell them somewhere, after all, they sell the stamens everywhere. Thanks for any help!

Here is a site that has things like that:

Stamens + Peps + Berries + Flower Centers

Some of them say they are stamens, but they look like centers to me. There are pages and pages of them.

Maybe they are called "peps".

Brilliant link, looks like they have everything.

If you search ebay for stamens you find several offers
