The pattern for making this can be drawn by yourself by watching my YouTube video.
Cut the interfacing into the shape of the pattern.
Attach the interfacing to the center of the wrong side of the outer layer.
Place the right sides together of the outer and lining and cut the fabrics into the shape of the pattern.
With assembled outer layer right side up, center zipper right side facing down (zipper pull at left) along top edge. Place the lining, right side down on top. Pin in place. Using your zipper foot, sew along top edge using a 1㎝(3/8″) seam allowance.
Open out, press pieces away from the zipper.
Place the zipper right sides together on top of the outer layer. Sew with an allowance of about 1㎝(3/8″).
Place the lining on top of the zip. sew with an allowance of about 1㎝(3/8″), leaving an opening.
Open out, press pieces away from and top stitch on 3㎜ (1/8″) away from the zipper, leaving the opening.
Flip the layers so the outer bag pieces are right sides together, and the lining pieces are right sides together.
Make sure the zipper start is at the top left.
Fold the lining of the bottom part into the outer fabric.
Sew both sides with an allowance of about 1㎝(3/8″).
Turn it right side out by pulling the fabric through the opening. And sew up this opening.
