I'm certainly not an expert, but I am addicted to them....
Celluloid, plastic, wood, and metal.
Coat buttons. These make a great base for layered button brooches.
Most of these are vegetable ivory, also known as Tagua nut.
Look at all this color. Fabric buttons are perfect for making bracelets. They're lightweight and stand up to being knocked around.
I keep these colorful plastic buttons sorted by color.
These are good for seasonal jewelry.
Metal buttons are also great for bracelets. My favorites are the little cut steel and picture buttons in the top part of the tray.
A platter of silver and gold metal.
A few military buttons.
I love mother of pearl buttons and the way they look displayed in jars. I keep them separated by size, color, carvings, and shanks.
Brown, white, and black plastic. You never know when one of these might come in handy.
Colored and clear glass buttons.
Black glass and gold luster in all different shapes and sizes.
Rhinestones and carved acrylic.
Assortment of metal and picture buttons
A little bit of everything.
