My youngest sister told me about this bag many years ago. You just need two squares of fabrice the same size, place rightsides together, sew all four side seams leaving an opening in one to turn out. You could use batting as well if you wanted to. Fold square on the diagonal to form a triangle. Measure the folded edge and divide into thirds and sew a seam at those markings 90degrees to the fold. The middle third forms the main part of the bag. Turn back the end sections over the centre section to form outside pockets. A bit of handsewing to anchor these sections in place. Make handles to suit. Hope you are able to understand my instructions.
