I cleaned up my quilt room recently and decided I didn't like the rulers on their sides method... takes up too much room! My solution turned out to be a sturdy cardboard box about 16" square and 2' tall and I put my vellum tablets, long rulers, shorter extra quilt hanging rods, quilt-line templates, etc., etc. in there. Even though it's pretty full, I can see what I want w/o digging.
My specialty rulers, along with small templates I've made are in my old dresser (so many of us have one!), my cutting boards are underneath the dresser along with huge chart papers (my sons engineering firm went for electronic only and I got a pack of their old paper!).
