The wood burl tables are made from 'slices' I purchased from a few different sellers on Etsy. Each one looks so different. The couch is a House of Miniatures kit that I just covered with a different fabric than the blue cotton that was provided. Same thing with the armchair. The footstool is just a piece of basswood covered with matching fabric and four wood 'beads' for feet.
Most of the ceiling fixtures throughout are made of thin basswood I purchased at my local hobby shop.
