I'm a bit late seeing this tip but I'm so glad it popped up as a random tip on the home page! I use different sizes of hair clips for plants too ... bought a pack of small ones at Wal-Mart a few weeks ago but I need to go to the $ store where I know I'll get more for my money!! I've also at times snitched a few larger ones from my hair supply stash when I'm too lazy to try to find something else to use for tying up larger stems/vines.
