I'll get the duct tape and save the pile of pennies that way, forgoing the humidity (sinuses are cracking with this forced air system) and I'll ignor the plume of hot moist air condensing over my driveway [...woooops!

I use them to cover my oil funnels, and pans in the Garage, keeps the spider webs and trash out of them. Tying Saplings, Tomato, Bean, Pepper plants up, doesn't cut into the bark / skin. Does work for getting Fibre glass out, but not in Front Load machines, just ties clothes in Knots. Wore old pairs when diving, so I wouldn't tear a $1k Wet suit or a $2K Dry suit.
