garden twine. i have a large new zealand flax plant, and use the lower leaves, split and dried, to tie orchids on trees, tomatoes to bamboo supports (and yes, we grow the bamboo for this), sun screens over lettuces, flowering vines onto porch rails, etc.
living in hawaii, frugally, i no longer pay for heating, air conditioning, storm windows, snow shovels, ice scrapers, pipe insulation, coats, warm hats, boots, sweaters, gloves, socks, scarves, earmuffs, stockings, shoes, business attire, dressy attire, nightlife, gym memberships, gym gear, gym attire-- you get the picture. yes, hawaii is expensive, but the savings are enormous!
