This particular string art is not nail art and was done by pulling the string through the back of the pattern. It is in very good condition and Im not seeing any areas where the string is messed up or missing.
The background is black felt. There are a few marks on the black felt. A couple that are a little more noticeable are shown in the last two close up photos.
