Why not sew or craft with old things such as buttons from a bygone era?   Here's an interesting vintage large celluloid coat button from the vintage war years of the WW1 to 1920's era. 

The size of the mottled greenish tanish button is 2-1/2" diameter. 

Concaved center with ornamental shape of points at either end.  Decorated center portion.  Back of the button is black in color with metal shank for attaching.

Condition is used with normal wear.
