The past few years, I have taken empty medicine bottles (the older you get the more of those you have) and stuffed surveyors tape into it until it's full. I cut a 1/16th" slot in the lid and feed the end of the tape through the slot. I've now got a huge supply of marking material that takes up minimal space, and doesn't unravel.
Bob, I've started buying brightly colored party napkins for use in lieu of TP. I also "never leave home without it". In my younger days, I had my share of one armed and short tailed longjohn shirts!!
