I have got inspired from wallet on the web. After have tried on paper I finally use thick canvas to finish this wallet, leaving the red trim exposed not only give the wallet character but also make it easy to sew. Still couple of details such as depth of credit card and bank-note slots need to be developed.
I have got grommets and puncher just for this project. It is fun to use and it give interesting details so I start to punch lots of my bags.
