The mobile is just for decoration, but the fish are a set for Logan's Easter basket that have magnets in them so he can 'fish' from the basket.
The book is a wonderful, bite-sized collection of crafts and just the basic principals of Waldorf Education. This isn't a new thing for me... just a re-exploration of the ideas that I have loved in the past. For a while, my children had no plastic anywhere in their lives. I enjoyed the idea of living toys and my kids had mostly wood and then baskets of things like rocks and pine cones we had collected on our walks to the grocery store. But I found it very hard after Alex was 8 years old to find any 'open ended' toys that he was really interested in. Just looking was hard... there were things like this and this online... but that was about it if you didn't really know where to look and didn't have liked minded people around you. (Now there are way more than there used to be. HearthSong Magic Cabin I can even find good toy stores around me for these types of toys in recent years.)
After we had started the flood gates of plastic, noisy things it was hard to stop. They may not help with learning at all, but you have to admit, some of those toys are just down right FUN.
In the end, for me, it is always about balance. Sometimes I go one direction and we watch lots of movies (esp when we are sick), play with plastic toys, and do no crafts at all... other times, we don't watch movies for weeks, and we have crafts going all over the house where wool, paper, wood, and seedlings abound. We are in one of those times right now. The times where my kids draw all day long and after they are in bed, I drink tea and do crafts like the ones pictured here. I like both times for different reasons at different stages in our lives. But the ones like these sure are prettier. ;)
