One of my favourite crafts women Carla De Jong, has many of her wood turned pieces in store. Carla is one of the most incredible toy makers you will ever come across. I recently did a Waldorf doll making course with her and made a few purchases from her home store. She doesn't sell wholesale so Koskela sells her products for twice as much as she does. Save your self a penny and pay her a visit here. Her toy tree houses appear at the Australian Museum in the kids space area if you want take them for a test run.
Koskela is really worth a visit, make it around lunch time as Kitchen by Mike, the in-store restaurant is delicious and affordable.
P.S. sorry for the quality of the pics - iPhone.
