Cut each fabric 30 inches X 10 inches.
This is an approximate measurement. It can be changed for a wider or deeper Saddle Bag.
Fabric #2 can be two different fabrics pieced together, but don’t piece them exactly at the 15 inch mid-point.
Thread, either to blend in or to show for the top stitching.
Velcro 3 inches in length.
Very thin batting or interfacing.
Embellishments or decorative stitching.
(HINT) A blind hem foot works well for Velcro. Don’t worry about stitching through both fabrics since this stitching will be hidden when the pocket is folded up.
