Oh my, but these buttons are as blue as you can get! They measure about 0.60 inches (or 1.5 cm) in diameter, glazed front and back. I call them my inbetweeners as they are just a bit smaller than the regular buttons, but not as small as the very small buttons. They are slippery, shiny and delightful - they don't mind getting very hot or very wet and their colour will endure as long as they will. High fired in my kiln in my small studio in Kent, UK, they are just the ticket to finish your project or embellish that cardigan you have worked so hard on....spoil yourself or someone you know who would appreciate them as a knitter, felter or seamstress. You will receive these 12 ceramic buttons as seen in this listing.
