This simple idea I came up with on my own.
To make doll furniture I cut chunks of 2x4 with a circular saw to make dressers, beds, couches, cabinets, refrigerator, stove (block), & grandfather clock. Just paint and use fine permanent marker for details.
For the headboard I used a piece of paneling with a jigsaw & nailed it to the bed.
To make the couch I used foam sheets to cover the block & wrap around back. I used a staple gun to attach.
