Now finally finished those three bags. I haven't made this pattern before. I had chosen it and bought the materials especially for them when my girlfriend said she really needed the girls to have bags that would be big enough to each hold a dozen books. Her daughters love to go to the library and I think Tracey finds it a bit daunting to try and drag home all their books - I happen to know that one time the older one reserved thirty (yes, 30!) books at the library and her mother nearly died when she got to the counter and found what was waiting for her! I love it! Tracey and I were at High School together and let's just say Tracey was the last person who I would have thought would have such a voracious reader for a daughter!
I think these bags will fit the bill! They are huge. Before they are gathered up they are the width of the fabric by about 50" long! They are called Fat Quarter Bags (as they are supposed to be made with six fatquarters on the outside) from M'Liss Rae Hawley's book "Fat Quarter Quilts".
