Well, I was thinking of labeling the slots for the sizes of the DPN's, but since I'm still collecting them, and reorganizing them constantly, I ditched the idea. I currently tell the size by putting them in order from small to large (first bottom row, then top row). Also, there are a few sizes I know just by looking at them, so it makes reference easy. Also, on the bamboo needles, the sizes are printed on the needles.
When in doubt, of course, I use my handy dandy needle gauge! (shown in the lower right pocket.)
Amigarabita-- yes I made the design, but it's based on other ones I've seen, so I didn't invent it totally. Although I did invent the trick for the back row, to hold long or short needles! (I'm rather proud of that!) :D
