using the inside of your pockets as a patch!
i don't use my back pockets much, so, i cut the material out and sewed it as a patch, you could also use iron on tape or fabric glue if you didn't want to sew.
i recommend using this with button up pockets because then you can either always keep your pockets buttoned up or even better, sew them closed by sewing along the edge of the flap. that way you never have a little underwear peak show when you bend over. but, it worked for me and going to the store turned into one less thing i had to do that day.
