Here is an unusual set of matching buttons, something I make rarely. These are thick and chunky but not too big around, good for a cardigan.

The colors are hard to distinguish, which means the buttons will work with many colors of yarn. The base is white with Irish green and cobalt blue grain, nearly like wood. They would work with navy, most blues or greens, or turquoise. These are chamelions, a good thing for a button to be!

Each button measures approximately 13/16" Diameter by just over 1/8" thick, A buttonhole should be 1" wide to accommodate this button. (2mm Thick x 2.0cm Diameter, 2.4cm Buttonhole Length) (Photo onscreen is not actual size.)

Oh, these are fun! Join the party.
