Please note you only need 4 - quarter pieces of fabric (not 4 yards)! I need to apologize to the person who originally posted this tutorial online (I don't have the name so I can't giver her credit! :( But if you end up finding it online, please let me know so I can thank her!)
by the way, I have this bag filled with 3 very large beach towels, sneakers, and 4 bathing suits!!!! I can only imagine what the 6-quarter bag would be like!
