A few things I did:
1. Arrange Bottles By Use
I have two types of bottles. The big 32oz or 128oz bottles that I keep to fill the little bottles and the little bottles that I will actually hold in my hands while painting. The big bottles simply refill smaller bottles but I have them all in the same space. Solution: I Put big back up bottles in a lower, harder to access shelf and the small bottles of the same materials in the easy to reach shelf. By creating a specific place where I keep second and third bottles or the much larger cartons of a medium, I will know where to look to see if I am truly out of something. This also clears up the easy-to-access space and will mean tripping over multiple bottles of the same thing while trying to grab something else.
