What you will Need

Step 1: Cut the Fabrics

  • Outer fabrics: one piece — 15″ x 13″ for the front, 15″ x 22″ for the back, two pieces that measure 4″ x 40″ for the gusset and strap
  • Lining Fabrics: one piece — 15″ x 13″ for the front, 15′ x 22″ for the back, 22″ x 7″ for the slip pocket, 14″ x 24″ for the zipper pocket lining, two pieces that measure 4″ x 40″ for the gusset and strap
  • Fusible Fleece: one piece — 15″ x 13″ for the front, 15″ x 22″ for the back, two pieces that measure 4″ x 40″ for the gusset and strap

Step 3: Add the Zipper Pocket

Create the front zippered pocket using the method in my adding a zippered pocket tutorial.  For my pocket I measured 2 1/2″ from the top of my front piece down and centered.  I pinned the pocket piece to the front piece.  I then measured 1″ down from the top of the pocket piece and centered and drew a rectangle 9″ x 3/8″ to accommodate my 12″ zipper. From there I followed the tutorial and added the zipper.

Step 5: Add the Gusset

Place the gusset right sides together with the front outer bag. Stitch the gusset to the front outer bag using a 1/4″ seam allowance. Stitch the other side of the gusset to the outer back piece in the same way. Turn right sides out.

Take the 22″ x 7″ lining piece and fold it in half right sides together. Stitch along the sides and partially along the bottom, leaving an opening for turning. Turn the piece right sides out. Topstitch along the fold. Place the pocket piece ____ up from the bottom of the back lining piece and centered. Stitch around the sides and bottom to secure. Create the lining bag the same as you created the outer bag.
