I'm currently working on quilted shoulder bags. I've designed them myself and with each bag I improve on the design. The one below in fall colors uses fabric designed by Lonni Rossi (Andover Fabric). The bags have a zipper for the main closure. The shoulder straps are adjustable from the inside of the bag. Right now I'm using decorative button hole stitches to make the straps adjustable but I plan on testing out grommets.
Below is the quilted shoulder bag with coordinating medium and small quilted zippered bags I made for myself.
