A friend’s beloved thrift shop find was munched by moths. I mended the holes, then covered them with Japanese Banku thread. For the bottom squiggle I was able to needle-felt the thread into place, but it would not stay attached for the top two…so I couched all of them.
(Apologies for the image quality – it was a gray day and getting late. And the top is actually an olivey green, just paler than the thread.)
