Twine. It's the ultimate multi-tasker. It's also super honest in its utility and simplicity. And when it comes in a container like this, it's display worthy, too. 

Sublime twine. I use it for tying my tomato and pepper plants, wrapping parcels, wrapping gifts (tuck a natural gift "garnish" at the knot. A sprig of rosemary or some-such is nice), hanging tea lights from the trees, tying around napkins, and for making a natural aromatic basting brush for grilling. Etcetera. Etcetera.

Look for twine in a container like this at your neighborhood hardware store. That's where I found mine.
