As promised, here is a picture of the majority of my jewelry-making button stash. There's a bit of an overflow in another box, and every time I think I have them all put away I find even more, but this should be just about all of them. You can see that I have a very nice variety of colors, even colors other than green. There's glass, metal, plastic, shell, and ceramic, vintage and new, mass produced and artist made, simple and quite fancy.
Of course, my favorites include the two translucent green insect buttons that I bought on my vacation to Washington, and the brilliant gold and green insect button that I bought from Nikia, and the shiny blue dragon which might also be from Nikia. The truth is that I can't remember where I got most of these buttons from because I buy them at all sorts of places. Quite a few have come from bins of mixed buttons that have to be dug through to find the best treasures, some are new Czech buttons that I've purchased from different gem show vendors. There's some Etsy purchases, lucky finds at fabric stores, and even some culled from old button jars.
By the way... you may notice that I said this was my jewelry-making button stash. That's because I have a smaller collection of buttons with holes for use on garments. Eventually I'll learn to sew and use them for that, but in the meantime I often replace the boring plastic buttons on clothes with pretty vintage ones. Oh, and there's also the pile of Turkoman buttons that I put on tribal bras and other dance costuming. I just can't get away from buttons!
