I think the theory is that everyone has to decide what size is too small to keep, but try to keep like sizes together, with some separation of species. I don't practice this theory and is on my list to do as well. Currently I have shorts in smaller tubs and anything 3' - 6' in a barrel, longer stuff is on the wood rack. Sheet goods are against the which has the rack near by (3' or so) for sorting sheets by leaning them against the back of the rack. I did just clean out my original wood scrap bin and plan to get it back in use as such.
