Quick question for you all. I've seen outlines of everything from wallets to flasks on back pockets. My question is how do you do this? I've recently started wearing my H&Ms again every other day. I usuall carry my wallet in one pocket and put a comb and the pen that I use in to take notes in the other, will the comb or the pen start to show up over time if I leave it in there. I'm considering buying a tin of mints, like the round altoid tins, to keep in my other pocket along with the pen. I this a good idea? Also, how long does it usually take to do?
