Needle cases are good too. You can quilt the covers for the bigger ones. I have a bigger one with a big variety of needles (I hand sew everything), and then a tiny one which just holds two sets of betweens (9s and large eye 11s), which fits into the little tupperware box I use for my hand-quilting kit. I originally used felt for the inside, but for the little one I just lined it with flannel and that works nicely too.
