The felt ball pit looks really neat, especially for sensory kiddos we might have, but anyone have any clue what size these balls might be? All I'm finding online are 2 cm which seems a lot smaller than shown here.
Make a rug loom with PVC pipe. Weave around top/bottom and sides of PVC to keep the weaving from pulling in. When done, just take apart the PVC and slip off the rug. What a great idea from Pink In Mind.
