get all the loose stuff into boxes (or if it is still boxed, keep it that way for now). figure out your furniture placement and whether you need more shelf units, etc. Once that is done, then attack each box--definite keepers go into their "permanent place", maybe stuff goes into a "little later" box/stack; and the "only if there's room" stuff into a 3rd stack (I'm assuming you got rid of the "I'm not bothering to move this stuff" pile before you moved--if not make 4th pile). Keep in mind that the last 2 piles need to be as big or bigger than the definite keepers!
I recently saw a showing of "Little Homes" on HGTV (think I have that straight--had control of remote so doing my own channel surfing!) and this couple had made a wonderful table built into the wall--a leaf folded up for regular table to sit at; then you could unfold the top larger for space to machine quilt, and the sewing machine rested in a cabinet that formed the back/wall of the table and had a nifty lift to bring it up so you weren't having to lift the machine. Under the space in the "front" of the table where the machine cabinet was built (the machine shelf was on the side) were deep drawers. All built into a trailer. Very cleaver idea.
