So a while back there was a thread going on drawer organisation and the use of Kaizen Foam. I'm not a fan of the stuff myself but plenty of people of disagree with me, and that's okay. I made the suggestion of using what you probably already have in your workshop; in abundance! Scraps of plywood, glue/nails/screws.
So as last weekend's weather was so brutally hot, I did something that did not involve a large a large expenditure of energy. I organised a couple of the shallowest drawers in my workbench that are used for marking and measuring tools. They aren't going to win the H. O. Studley Memorial Annual Prize for Innovative and Aesthetic Tool Organisation (I just made that up, but we should totally create one!); but here they are.

I settled on 7mm wide plywood trips as being wide enough to use my 23g pin nailer accurately enough on and not too wide as to waste space.
As they are just held by a couple of pin nails, they can be pulled up with a pair of pliers and rearranged as you need to.
I'm not sure about that row of slots for metal rules and may re-do that using a solid piece of wood and cutting grooves with a plough plane. Or I may not!
I bulk cut the strips from the plentiful supply of 12mm plywood scraps on the bandsaw and then made them nice, smooth and even with the drum sander. I then cut them to length with a handsaw and round over the ends on scraps of sandpaper.
