I have always wanted to sew a box bag & now I have made these for Christmas. I found a site & a utube video with instructions & followed them to the letter. How to make a Zippered Box Pouch | with Jennifer Bosworth of Shabby Fabrics
That said I I do not care for the raw edges only Sergered on the inside so after doing the spider-man, one with yellow liner I decided to alter the process by adding bindings to all of the insides. Unfortunately I did all the bottoms first so I could not add the bindings there. I will know for next time.
I am happy with these & will make more. you can make these with just 2 fat quarters of fabric & some heavy fusible interfacing & a zipper. these will make two each if you make them the same sizes as the video. I think they will be well liked & quite useful too
I signed up for a class on how to do these bags. Yet to make one.
