Go to Henrietta's Handbags, she shows the list of supplies with each pattern. I make lots of these bags and use about 2/3 yd for outside bottom part, lining and outside pocket and about a 1 1/4 for the outside top, inside pockets and the handles,( I make longer handles you need 10" instead of 5"). I also have extra to make a checkbook cover, tissue cover etc.
You will love making them.
