I have been working on a notebook cover for a friend of my daughter. I decided to add a zippered pocket to the inside flap so that she could carry her banjo picks with her. I guess not everyone needs to carry around their picks with them, but this would also be great for pens/pencils, change, or any small objects.
1. Measure you zipper and add 1 inch to this measurement. Take this measurement and cut out a piece of fabric that is the length and width of this measurement. For instance, if your zipper measures 9 inches long, add 1 inch, bringing your measurement to 10 inches. Cut out your fabric 10 inches long and 10 inches wide.
2. Unzip the zipper and place it right side down on the right side of the fabric, making sure to center it along the edge. Sew down the side of the zipper.
Note: I used a zipper foot on my machine to sew close to the zipper.
3. Fold the fabric in half, right sides together. Pin the un-sewn side of the zipper to the right side of the fabric and sew.
4. Zip the zipper closed (I left mine partially opened so that I could easily open it when I finished). Press the fabric flat, making sure that the zipper is centered. Sew across the top and bottom leaving a 1/2 inch seam allowance.
5. Turn inside out. When I sewed it onto my notebook cover, I simply chose a matching color thread and sewed around the very edge of the zippered pocket.
