As most of you know, I am from the old school.
Once upon a time, it was commented that you could use Clear, Sally Hanson's Hard As Nails Varnish on very small holes or very small tears that could possibly lead to future fraying. The only issue with using it, is that the clear dries very shiny and you have to risk dulling the finish by touching it before it dries, for it to not "STAND OUT" too much. I am not sure If they have a "Satin" finish or not. I have used it where I had to make a small repair, hand stitched and I coated the repair with the SH and it keeps the repair from future spreading and it worked great. Have any others tried this or have comments about it?
