One way to reuse prescription bottles is as a portable sewing kit. Put a spool of thread into the bottle, pierce a small hole in the lid and run the thread end out the lid. Put several needles and pins, however many you might need, inside.
This way I can take sewing projects with me and finish them while I am waiting for appointments, etc. When I have a number of items to mend or hem, I either stack different bobbins in the bottle in different colors or use gray thread, which blends with almost any color.
I work for a guy who I know couldn't sew on a button to save his life. I made him a little sewing kit with pre-threaded needles (I threaded them) in black and white, and extra shirt buttons. I then taught him to sew a button, and he now has everything he needs at his fingertips.
