I don't have the buttonhole nor button on this yet, and one picture is blurred (showing the flap up and back pack 'stuffed'. One only shows one strap up but both straps are the same. I used 3 red and other color combo's to make a child size back pack, and wanted to share it. I thought my young great grands might like one. I just sent the mama's a picture of the 3 views.
I just used rectangles of colored fabric I already had in a stash. I supposed a person could quilt some fabric and make one with it as well.
