tomato clip wire

[wally mcgee]

Last year I purchased some nylon based twine from a well known seed/garden online store that was advertised for use with the clips.

I kept going out to my hoop house , mid summer, to find the twine had broken and the 7' plants on the ground. I think the sun was dry rotting it.

Anyway, this year I am just using plain old nylon twine bought at Ace hardware. So far so good, but not ideal.

Where, do you get the wire used for this purpose? And what kind is it?
