I've heard mention of people stacking trays in small darkrooms (such as mine) and was wondering if anyone has any links or ideas on where to find them or how to construct them.

My sink is quite narrow and short, and if I want to go any larger than 8x10 I'll need to stack at least two of my trays. I'm thinking of looking for something off the shelf, possibly something like a wire storage rack system you might use under your sink or in your closets. They are usually coated with plastic and pretty stout to stand up to being wet etc..

Any ideas or suggestions would be helpful. Thanks.
