i got a book about organizing your space...i don't remember the name of it, cause it is out on loan again..
but what they have you think about is the ergonomics involved and how to be more comfortable.
they also suggest you use graft paper & make right size pcs for the furniture you will keep...thats what i did & it worked out really well...i have the ironing table set up btwn my dd & my machine, which are back to back, so we can both just spin around & press...
i loved the graft paper idea, because usually i move things around 1/2 dozen times to get it right.
