DIY Lighting

I need to start doing some more DOING and less thinking about what I need to do. I've got a million and one ideas spinning around in my head. Should I stencil my walls? Should I stencil my floors? Should I make a pelmet for my office? Yes, all these are all on the to-do list. Also on the to-do list: a DIY light. I've needed a new light fixture for my office and one for the dining room for quite a while now, but I'm not really sure exactly what I want, and the ones that I have found are pricey. I came across some pretty amazing DIY light pendants. Check out these string/hemp/yarn/jute globe pendants. I'm not sure that these are exactly what I'm thinking, but I like them. I'm worried that it will cast a weird light in my office where I really need to be able to see well.

I fell in love with this beachy Malibu Chandelier from Serena and Lily, but it might be too small for either space, not to mention the $900 price tag. OUCH!
Although this one does look like a really easy DIY.
I love the tassel detail.

I'm sure you've seen the turquoise similar version. And I've seen some not-so-great- DIYs of it. 

But I have to say, this one is very impressive:

I've also been thinking that I should try to do something with perforated sheet metal. It comes in all kinds of cool patterns. I'm thinking it would start something like this:

And add a liner and a diffuser. Has anyone attempted to make something like this? I think perforated sheet metal is the same stuff that you use to make radiator covers. Any other great DIY light options I may have missed?
