Q.Correction On Your Duct Tape Article
Apparently you have never actually tried to use duct tape for many of the things you suggested. If you had, you would know- DUCT TAPE DOES NOT ADHERE WHEN WET. Or when the item you are trying to tape it to is wet (such as a flower pot). In no time at all you will see the outer layer flapping in the breeze, and the grid of stickum sitting by itself where you had carefully put it.

Interesting. It must be the brand. I have a pot that I made out of duct tape, alone, 3 years ago that is still being used for one of my trees! The pot and saucer, both, are made, solely, of duct tape. It gets watered, daily.
