Early childhood is the best time to introduce your child to your personal sense of quality and tastes. Eschew low-quality, mass-market material made from plastics and paints of questionable safety.
Good news might be coming up soon! I may have lucked into a parent who might be able to make the floor mats in traditional Montessori green. Right now, I can’t even find them for product photographs for the albums.
This is a great idea. So many of the cheap plastics are toxic too.
