Cheap storage solution for OCD types like me

I'm a neat freak when it comes to my shed and these things make my shed even neater. I have 3 sets of these multi use racks and use them for timber and tubing, I have a couple of kayaks on them as well, as well as other long bits and pieces that would usually just lean against the wall. A cheap and smart way of organising stuff to satisfy my OCD.
