I use Excel to keep track of my figures. They are sorted by year, then series, then figure name. When I do a new display, I try to keep my figures in that order as I check them off the list as I put them up. That works out OK most of the time, but I try not to have too many of the same figures next to each other.
I’ll display all the variations of a figure, like Batman, Superman or Green Lantern that I have, but will not put up duplicates when I don’t need too.
As I get new figures, I try to keep the order the same and expand the space, but with JLU I had to put some figures in randomly. Some of my figures weak ankles gave out and I had to move them around in the display.
I also like to keep groups together like the Green Lantern Corp and Justice Lords.
I put as many accessories as I can with the figures. I hate small accessories like Batarangs as they pop off and disappear, so I tend to glue them to the figure. Since most of my JLU came from 3 packs, most do not have any accessories.
