2 Train Making a Wallet
While Prototype my wallet I started from the main issue the client had. That was the fact that money and cards may fall out if held in certain ways, she also wanted to make sure it would fit in her pocket. I started the prototype with a flap that covered a place to store money, and a tab to keep the cover closed. As I progressed I added further pockets and an ID window for better functionality.
After completing the prototype I immediately realized that the closing apparatus was not going to be sufficient. It was difficult to close and if the wallet held a lot of things it would struggle to stay close. Future prototypes would incorporate a button or a string similar to those on manila envelopes.
