Glass beds can be used for making reflective paint, signs, crafts or anything else you want to be reflective.
Simply mix 5 - 6 pounds of the beads into a gallon and mix thoroughly or after painting your item sprinkle generously over the paint while it's still wet (most people like this method better as it reflects more).
Tip:Put a drop cloth below where you're sprinkling them so you can catch the ones that bounce off (there'll be a lot of them) so you can reuse them.
