You can buy packs of them at JoAnn Fabrics stores in the Button and Notions area.

Or try The Bee Lee Company. Call 1-800-527-5271 for a catalog (I don't think they're on line). They carry all kinds of hardware, jeans buttons, Western buttons, snaps, rivets, jeans top stitching thread, jeans zippers, etc.

If you're talking about snaps, no it's not possible to reuse them. If you're asking about buttons which are sewn on, yes, it's quite easy to reuse them--a habit my foremothers did all the time.

Thanks for the help guys.
Marg411, it's the fasteners on a pair of pants that I'm talking about. I was afraid they wouldn't be reusable.
It's just that as I was going through some of the kids outgrown clothes, I noticed some of the cutest Mickey mouse fasteners that I really wanted to use for an embroidery project. OH well, I guess I'll have to figure out where to order them at. No JoAnnes here, only A Hancocks and there stuff is limited. I'll order a catalog from Beelee and see what they offer.
Again, thanks for the help

They should also be available at Hancock's. They're sometimes called bachelor buttons.
