i don't use altoid tins anymore for mine PSK, but mine way of putting fishing wire is to wound it around a creditcard ( a discount card in mine case.. ), wenn i got enough i put 2 pieces of tape on the line with the ends fold double, after that i slide it off the card and put it in mine kits. if i use it, i take would out a creditcard sized card or something else, and slide it on and unwind it. Make sure you wind the line on a proper way, i cut a V shape out of card board and tape it on the card to creat a slot were i can put the line beter on.
