i'm kind of in the same boat. what i've taken from waldorf off the bat is the richness of nature, and using nature-found objects in our play spaces. toy minimizing, and beautiful organization. what works for us is simplicity, as we have a small home, limited $, and a ds who gets distracted easily. must haves for us: sticks, acorns, rocks, shells. art supplies, plenty of them. we keep out continuously on our art table: oil pastels, regular crayons, block crayons, markers, glue, scissors, a variety of papers including recycled stuff. nature time and art time are essential to our daily lives.
ds has his own, simple kitchen. he's very proud of it. he cooks all the time in it, using stuff he brings in from outdoors mostly. i've sewn a few things as toys, which he loves- pancakes especially. before we got the kitchen, he used to use various kitchen items- utensils, pots, rocks, at his art table and cook as well. looking back, the kitchen was not entirely necessary, but it does make for a beautiful, well used toy in our living room.
