The see through net bags ( e.g. from Chico's ) I reuse when I give a gift of my jewelry. The bags are all sizes...if only a large size is available, I will wrap the piece in a scarf and tuck it in whatever is available.
For the velvet / suede ones: I use these to hold the car fobs to DH's cars and my car. I suspend them from one side of my shoulder bag. If he loses one or needs to leave one with the car service desk, I have one readily available.
I also use one to store Pennie's; another, nickels; dimes; etc. until ready to cash them in. One diner loves to get change so I pay in coins.
We make a living by what we get. We make a life by what we give.
