I will not make a bag and not use it. It's very easy to cut and sew through. It makes a bag stand up by itself, but it's not stiff. I made a large bag to hold my knitting and it's held up very well. I just ordered 3 yards thru Massdrop. I have it in both black and white. I really suggest you try it, I'm sure you'll like it and prefer to use it over batting and interfacing.
