I'm putting together a mending kit for my BOB and was wondering what things you would add. So far I have... a box of pre threaded needles and threader, an assortment of upolstry needles, safety pins, 6 velcro zip ties, 2 large buttons and 3 small buttons, a pair of embroidery scissors, a tube of krazy glue, and an iron on denim patch. I have it in a tri fold nylon wallet with a velcro closure. I have some extra room in it so I was wondering what else I could put in it.
