I wanted to make you a messenger bag sewing tutorial, but I wanted it to be a little…extra. So I added a Diamond Art creation! I’m so happy with the finished creation. You can choose any Diamond Art piece that is 8 1/2″ square or smaller, and any fabric that makes you happy for your bag.

Some products used in this tutorial were provided by Leisure Arts and Clover. All opinions are my own.

This messenger bag sewing tutorial uses all rectangular pieces of fabric, so there is no pattern to cut out, just a list of the rectangles to cut out. I highly recommend using, tailor’s chalk, a 90° ruler and a long ruler for drawing out your rectangles in order to make them square and true to size.
