In reply to my post, calkin and Peter Mielke mentioned some everyday problems they have solved through origami, like making a CD case when you have a CD and no case and binding pages together without a stapler, among others.
Thank you very much! Those are awesome examples. Can you all also help me think of daily problems you still have and that you believe a product made out of folded sheets -of some sort- could fix? That way I can choose one and try to create a product for the end of the course. Thank you all : )
