I love using Popsicle sticks for a lot of things. I personally cut the rounded edges off of 500 Popsicle sticks to lay flooring throughout my minis house. I have used them to make furniture and you can too! Glue, Popsicle sticks and patience!
My beds were made from cut to measure pieces of foam board then framed in Popsicle sticks.
Once you have constructed your furniture pieces, you can paint them, then add cushions and tablecloths; bedding and pillows.
