Thanks for all of the suggestions. I'm being really picky though and still haven't found just what I want. Most of the problem lies with the fact that my hoses, couplers, and tools, (while most being labeled 3/8") vary a great deal in size. So if I make a holder for the largest coupler the smallest will fall through it.
I tried a spring loaded rake/broom hanger from the hardware store, but the spring is WAY too strong. Can't be used easily with one hand. I could swap the spring with a lighter one, but that seems like a lot of work.
Anyway, not a big deal. Just getting tired of picking the hose off the floor after it slides off wherever it was laid last!
When/if I figure something out I'll post it here.
