Here is a bow screw's button that had three missing mother of perl pieces. The unusual thing about this button is that each piece was seperated with a small piece of ebony. A couple of those were also missing.
The easiest way to repair this was to find a matching mother of perl slide. Then cut off small pieces that were the same width as the facits of the button. Then just hand fit them.
