Copper enamel torch fired buttons....round  and square ones are 1" in diameter, except the round red buttons are 1-1/8". Each button is cut from copper, filed and buttonholes drilled. I then layer enamels and fire them onto the copper. The backs are brush finished copper that I have sealed.
 
These handmade buttons are washable. I recommend handwashing or turning the garment inside out. Enamel is glass and if banged hard enough could chip! Each set is one of a kind, however additional buttons in the color /patterns can be made. I can also do different colors if you are trying to find something particular!
