if u mean u want to put distress in your jeans, u need to find about a 90 grit sandpaper. and then u use it horizontally on the fabric. It will take the blue denim off, but leave the white thread there still. or if u want big holes, or slits, like A%26amp;F jeans, I'd use a knife and make multiple slits in one area.How do you cut holes in your jeans with a cheese grader?
