Re: Low buck projects- Let's see 'em!
I just finished these shelf/pouches. Stained poplar from home depot, brass nails and screws, bungie cord from REI, and blue cloth from a tablecloth (polyester or nylon if I remember). This project has actually spanned more than a year since I've been pretty lazy. I also didn't even have power tools when I started and used hand tools to cut the wood (partly why I chose poplar, cost was the other reason).
One thing I've learned on my boat is that rigid things and containers arn't well suited for the curves and small spaces. The first toolbox I bought couldn't fit anywhere in the boat. So I came back with a toolbag which can stuff where it needs to go.
So this is intended to be a combination between a pouch, which are really practical but I don't love the looks of, and a rigid shelf. I think it's going to work out well.
