I made this little bag to hold the accessories that I need for my mountain dulcimer, but little knitted bags are super handy for tons of things. I added a little pocket to hold the picks up out of the bottom of the bag. You could do the same thing for jewelry and use the pocket for earrings or rings. There is also an accompanying video on my YouTube channel on using a fringe twister to make the drawstrings.
