Optional: strapping for shoulder strap 1-1 ¼” width
Use ¼” seam allowance unless otherwise specified.
Liner – with right sides together, sew sides and 1.5” in on each side of bottom (back stitch).
Pocket cuff – press under ½” along the long edges of band. Open up fabric just pressed, fold right sides together and sew along sides. Turn right side out and press under open edges. Stitch along bottom of band.
Pocket – fold right sides together (so it measures 6.5” x 8.25”) and sew along sides. Turn right side out and press. Slip pocket cuff over top edge. Position pocket.
Cover –Lay batting on wrong side of fabric, and pin in place.
Attach pocket to cover. Position pocket on center of back approximately 1” from bottom. Sew around left, bottom and right side, making sure to backstitch at start and end.
Fold right sides together and stitch along end (or short side). Press seam open and turn right side. “Fancy stitch” over seam with contrasting thread. Turn inside out. Flatten out with the seam centered on one side. Sew along the bottom edge. Turn right side out. Even off and trim edges to 17″ x 11″.
Flap – place flap cover and liner fabric right sides together (rectangle should be horizontal). On each side, mark along the ¼” seam allowance 2.5” down from top edge. On the bottom edge mark a centered spot ¼” up from edge. Tape the button loop in place at the center point on the bottom of flap (the loop part should be on the inside taped down and the ends sticking out). Sew a ¼” seam along the side until you reach the first marking, turn and continue at an angle to the center mark at bottom and continue up to final mark on other side, and along side seam to end. Turn right side out and press. You should end up with a triangular-ish shape with a loop sticking out of its point.
Center flap on outside back of cover fabric (the side the pocket is on). Optional: insert shoulder strap between flap and cover fabric with ends facing up. Baste with a ¼” seam allowance.
Using a pencil or pin, mark the center top on each side of the lining. Mark sides of the cover as well as the center of the side opposite the seam.
Slip outside fabric into liner with right sides facing each other. Match up center and side marks and pin in place. Make sure flap (and strap if applicable) is down and out of the way. Sew a ½” seam around the top edge. Turn the lining by pushing the cover down the opening at the bottom of the liner and the lining up over the sides of the cover fabric. Don’t tuck lining in yet.
Place 2 pieces of Timtex on top of each other. Sew a scant 1/8” seam allowance (you can safely sew close to edge and it will hold) around the sides and bottom. Turn right side out and press seams flat. Slide Timtex through the opening in the lining and fit snuggly into the inside of cover. Sew bottom of lining. Push the lining into the Timtex™ and position until all edges and seams line up. Topstitch around the top edge.
