Salomon believed that of all the basic crafts, woodworking best fit general educational purposes. Because most schools would not be able to afford to introduce a wide variety of crafts to their students, the overall needs of education would be best served through woodworking sloyd. He adhered rigidly to this plan, and it wasn’t until his death that textile and metal sloyd were added to the teacher training at Nääs. It was also clear to Salomon, that mastery of a single craft was more important than a cursory exploration of several crafts that did not offer the student the opportunity of reaching a point of mastery.
