The life span of your average pantyhose is, what, 2 months? I have actually had some pantyhose for years, but thats because I only wear them a couple times a year. So lets say you get 5 good uses out of a pair of pantyhose - what else can you do with them?
I did a little research and found a bunch of ways to reuse your old, tared, lots 'o runs pantyhose.
Step 1: Arm Tattoos
I love this little trick. My friend was as basketball player for halloween and wanted need fake tattoos to complete her costume. She didn't want to draw on her arm so she drew her designs on a pair of nude pantyhose and wore it on her arm.
I tried this and tried to trick my roommates. I drew a flower on the pantyhose then put it on my arm. When I showed it to each of my roommates they were like, "thats great you drew a flower on your arm....". When I pulled down the pantyhose they were like, "WOAH I TOTALLY THOUGHT YOU DREW THAT ON YOUR ARM". True story - and it worked on 4 different people!
