Sew a Bag with a Compartment for Shoes and a Water Bottle

Using the top fabric and lining pieces that were cut in half lengthwise, sandwich the zipper tape between the right sides of the lining and fabric, lining up the edges the fabric and the zipper tape.

Using a 3/8" guide, sew a sew to hold the fabrics and zipper together.

Press the fabric back from the zipper to expose the zipper.

Top stitch near the sewn edge, sewing through both fabrics and the zipper tape.

Repeat for the second side of the zipper.

Measure the finished piece to be sure it measures 20" by 7". Trim if needed or take apart to correct your seam allowances.

Baste the edges and press.
