Yet another use for this PET stuff.
Got a bundle of sticks you need secured for transport?
Need something strong to hold some poles together TIGHTLY?
Hate untying unruly knots?
Hate knots that come undone on the highway?

For this instructable, I will use one piece construction, but it can be cut into long strips and used similarly.

If you cut this stuff into strips as in Rope,cord,string from Recycled Water Bottles! by bara1962, you will not be limited to the tube diameter and will be able to secure larger irregular shapes, but you will also lose the strength and “convenience” provided by one solid piece.

Note – Various bottles can be cut into tubes of varying diameters/shapes and lengths as required.
