This bag was made from unbleached cotton, which has good strength and thickness. It is also easy to sew since it is naturally a stiff cloth. The flap was made from Indonesia batik, which I really love for it's rich delicious red.
In the end, it's just a heart-warming bag, not only because I finally able to make a messenger bag, but also because it's a perfect bag for me. I would like to make another one soon, and share the joy with you.
Happy sewing everyone! ^_^
