- a specific set of samples that illustrate each of the procedures we did linked to the notebook
- a cloth color chart illustrating all the mordants crossed with all the dyes
- samples of your own, on your own cloth, that utilize what you’ve learned to make this new knowledge
Most importantly, this week is meant to address students’ specific needs so bring your own interests and questions
