This was my first trial pattern for this geometrical bag. 

This bag was designed by folding and cutting paper and is made from one pattern piece. I did not sketch for this  bag until after the design was finalized and I needed to work out details such as the flap.

This is a paper mock- up I made 

I added a square of stiffner to the bottom of the bag to help it sit up and give it more shape.

I made many mock-ups for the flap to help decide what looks best. In the end, I decided to keep it simple with only top stitching.
