My sewing room is about 12x12. In it I have 3 etageres (1 with blender fabrics, 1 has quilting-related books and my TV and 1 has project bins and magazines), a computer table, ironing board, cutting table, small bookcase, and my large Horn sewing table that stays fully open (with four roll-around drawers underneath). The room has a narrow wall-to-wall closet that has batting on the top shelf, and filled with shelves for UFOs, backing/background fabrics, and specific collections (black and white, batiks, florals). That's a lot of stuff for such a small room, but I drew a grid and all the furniture pieces to scale and arranged and re-arranged until they all fit comfortably, before putting anything in there. On the walls I have two bulletin boards, a large design wall, wire shelves for (fq's, jelly rolls, Kaffe fabs), quilt hangar, clock, file hangar, pictures, nick-nacks, ruler holders, and on the floor I have a tote for kits I've gathered, and one for to-be-quilted projects, a large trash can and tall open laundry bin for fusibles, interfacing, stabilizers, etc., and a vinyl shoe holder on the back of the door for threads. I wish I had more room, of course, but I manage very nicely
Wish I could get an overall picture, maybe I'll work on it!
