Why wouldn't you just buy a spice rack? They come in several varieties, and are reasonably affordable. I would check craigslist, garage sales, or even auction sites. That should work for most of your glitters. I would also use a speed rack, which is designed to hold speed pour bottles for your colorants. I know there are several places on line you can find these things, probably reasonably affordably. i like www.overstock.com
for these things. Just throw the dried crap they call spices out, give it a bit of a wash and move on. Should work a treat.
The advantages to doing things this way are the rotating spindles make it easy to find the glitter or color you want. The tops of the jars are nice and wide so you can almost always fit a measuring spoon in there for accurate measurements.
Hope it helps
