Ummm....you could dye your legs black? Then the holes would not show or you wouldn't even need to wear tights.
Tights that have gone beyond the pale....
Use them for plant ties
make a braided rug
stuffing for dotees, ninnis, stuffies, dog toys.
braid them for rope or a belt
make creepy hanging moss or black cobwebs at Halloween
pull over your head and rob a bank or terrorize the neighborhood
LOL...there must be some use for them!
