I've used the odds and ends than come off bales in the garden to tie up the 6 x 10 foot chunk of concrete reinforcing mesh to posts for peas or beans or tomatoes to climb on. And since we live on a windy hill, I use pieces tied together to make a long string to keep the vines from flopping off the wire, pea fence, etc. At the end of the season the twine can be tossed into the compost pile with the dead vines, and is gone by the time the compost is finished. It weathers to a grey, and is unobtrusive used to support floppy flowers, such as yarrow or peonies by intertwining with support twigs (shove 3-4 branches pruned from tree, like apple suckers around plant, and wrap with twine). The compost pile is made up of pallets attached to steel posts with the twine. Three pallets form a U, and there are 4 consecutive bins. A "door" is made from a fourth pallet to hold the compost stuff in place and keep the chickens from scratching it all out. It is all held together with twine. Wire would be more permanent, but then I'd have to go buy wire, and it is no big deal to replace the twine when the bins are emptied. I don't like to use the plastic twine, as it eventually shreds and I find shreds in the garden soil.
