Recently I had the opportunity to speak to two Australian Montessori suppliers and see some of their new infant/toddler materials. All of these materials except the bells are by Gonzagarredi. While these materials are made specifically for a school/community environment I think there is plenty of DIY inspiration. The bells however were in my price range (and I have them on backorder). I love the adaption of the bells for toddlers. The Screw/Unscrew is really clever and the fabric box is genius. Beautiful.
