Half Hexi Tote Bag Tutorial

My husband recently bought himself a new toy in the form of a 3D printer. So, I have been thinking of ways that I can make the most of it in my sewing room and have tried out a few quilting templates. We have tried a few different designs and shapes including this half hexagon. I saw a cheat hexi quilt years ago and always wanted to give it a go so I thought this shape would be a great place to start.
