Pantyhose can be reused for a few things. When I was growing up we used to put our jumpers on one then hang it on the line - no peg marks or stretching. They can be used as plant ties, hanging onions & garlic, a tennis ball in one then tied to the clothes line to be used with a cricket bat, tennis racquet etc or as a toy for the dog.

Spray bottles, relabled and used for spraying pests or cats
