Mine has a black background. I defo think you can see the figures best with a plain background. A mirror looks good, had that in a figure cabinet, you can see the back of the figures.
I like to keep it to a single colour background as well, I think it makes the figures the focus & makes them pop the best, you could go for the yellow on the 77 backs to add a splash of colour?
Just managed to find the image of mine at the last house
Love seeing this Edd, I've still got my loose figures in an ancient Ikea Bertby with a plain back.
What I found interesting is that you have ROTJ at the top and SW at the bottom. Is this due to 8D8 and the spacing or you being a relative youngster and Jedi is first and foremost?
