Instead of buying the stretchy hair ties, I've been cutting cross-sections of panty hose! Why do I even have panty hose, you ask? To tie up tomato and other plants. I just cut across the 'tube' of the leg part in 1/2" or so pieces. One leg yields many! I double or triple wrap each tie to make it the size needed, either/both before putting on, or as I put it on. Gives me joy to repurpose something I could never relate to for its intended purpose.
