So folks, this is where the magic happens! My opa actually built this desk when my dad was a kid.
There's all sorts of things that create a good work area. A desk is a great place to start as it creates a static work area where you can leave things set up and store all your stuff.
These type of shelves are a great buy. Your local hardware store will have cheap shelf planks and brackets. Use a level, drywall screws for the wall, short wood screws into the planks and buy the extra support by getting a bracket (or more depending on length) for the center.
Also take note of where I actually paint - an old beige steel (for weight) external zip drive with rubber feet (anti slip) with two blocks of wood on top, then a blue paper towel (max absorbency) then a glass palette. (great for mixing on) I'm a tall guy and this raises my painting area so I don't have to lean down as far. (Your back knows what I'm talking about)
I've been thinking about putting 2 screws on each side and a small shelf to give me some extra room in there.
Saving containers is a great way to keep everything organized too. Super glue often comes in plastic sealable containers the same size as what you'd spend $5 on at a hobby shop.
I know I've got a lot of stuff. How do I afford it? Sales and surprises. You'll bankrupt yourself if you buy it all at once. A little here and there is affordable, especially if you find it on sale or you're out somewhere and just happen to see a deal.
Sink a screw into the wood, attach a magnet to it and your tools to that.
Super simple organization.
