講習用に、材料、折り図等をご用意される場合、教室内で必要経費（用紙代、コピー代等）を集めることは可能です。教室プログラムに記載しますので、正確な金額が分かり次第、事務局にお知らせください。If you are providing materials, diagrams, etc. for the class, you may collect the necessary expenses (paper cost, photocopying cost, etc.) during the session. Please let us know the exact amount as soon as you know it so that we can include it in the program sheet.
