The wall is cleaned, patched, sanded and painted.
Here is the IKEA shelf. It is 4" deep, and has a groove.
Finding the wall studs for six shelves. Yes, the easel is 8' tall.
Mounted and tested using the only painting that matters.
Populated. 24' of shelving, and I need about twice that, there are already painting behind other paintings. There are another 29 paintings that just don't fit. Need more shelving.
This is what I wanted, to be able to see them all (29 others notwithstanding) at once.
