I also feel your pain. I have started a major clean-out of closets and dresser drawers in preparation of reorganizing my sewing room. I wanted space to put things that are in the sewing room that are really "sewing" but everything else was so stuffed that there was no room. I am proud to say I am now the owner of EMPTY SPACES in closets and dresser drawers!! And I found some fabric I had been looking for for over a year.
So hang in there - I am sure your box will eventually turn up!
