Those pesky needle holes left when one does some "unsewing".
In an earlier life, (ie years ago) I used water and vinegar in a spray bottle to press seams with needle holes after removing a seam, and WOW the fabric was like "nbs" (never been sewn - no needle holes).
That was the good news, now the not so good news....I do not remember the ratio of vinegar to water....HELP
