I did a search of the site to see what had been said about moth repair before. It didn't include this product, which has been put forward on another reenacting site
A few people have used it to good effect. Anyone on here familiar with it?
I quote here from user "Georgia" on the forum:
"I think the main thing to remember is not to use too much. It goes a long way. For moth holes, take a tiny piece of material from somewhere else on the garment, shred it or cut it into tiny pieces, mix it with a few grains of the powder and iron it into the hole. Make sure there is greaseproof paper on both sides of the garment, (between the garment and the ironing board as well as between the garment and the iron) or you will end up gluing the garment to the ironing board or killing your iron! Unlike wonderweb, you use a dry hot iron. "
