I recently saw a tv show that made furniture for doll houses. She used foam blocks, covered in batten and extra cloth she had on hand, for beds, couch and chairs. She use 1x2 wood blocks for the bed frame, kids play toy blocks for kitchen table chairs, etc. Good luck.
A good place to start is www.printmini.com. Jim's dollhouse pages, lots of cute items to print out & in different sizes. There is a link at the bottom of page for mini print ring & it connects to lots of other printable sites.
