Step-by-step guide on sewing a trapezoid fabric bag.
I tried the pattern myself and it turned our fine. I used thin fabrics and put a carton inlay inside the bag, due to the stuff I want to put inside. If you want it to be stiff itself I recommend either using fabric that is thick enough or sew in a middle layer for more stability.
