My starting point was if a product has a function but it is hidden, how I can overcome the limitations of such a design. The bag appears to be the same as other bags, but if one section is pulled out, it will be a different shape, or its features can be changed if it is reorganised. So I thought origami is one of solution if I use it. The origami is from the flat paper, it can have a lot of features according to how it is folded so it can be something from nothing. I thought about flexible products with how to be folded and it has various ways to use with folding. For example, it is just plain surface before fold but it has special pattern with folded some part. I think this can be good example to show what my concept is, and how I want to make accessories. The other idea is make pattern with folding guide line. It will be also foldable part and that guide line can be one of design for product. It has three types to guides. These guide lines are for cutting, folding to inside and folding to outside. It can be unique patterns for making.
