Gentlemen,
On the ETS forum, I learned how to take an old Wally World “PrePay” style, credit card, and wrap a supply of Duct Tape to it. Whoever originally thought of it had a Great idea! A readily available supply of Duct Tape in a “Flat-Pack”, that was capable of being carried in a wallet or carrying case. Practically no wasted space, or weight!
Well, when I went to wrap my card, I noticed how much wider the card was, than the Duct Tape….about 1/2″ of space left over. So, it was back to the garage, for my Electrical Tape! If you wrap the Duct carefully, even with the edge of the card, there’s enough room for a wrap of 1/2″ Electrical tape, which will just fill up the card!
Hardly any wasted space on the Card now!, and I have approximately 10′ of Duct Tape, and 10-12 feet of Electrical Tape! You just never know when one or the other will come in handy!
