Close Zip Pouch Ends

  1. With wrong sides out, close zipper and lay flat. Ensure zipper is parallel with edges. Zipper should be evenly spaced in the middle.

  2. Lining up the bottom edge, sew one end closed with the 3/8 inch seam allowance. Being careful not to break your needle, sew over the zipper.
    3. -
  3. Flip around, smooth out and ensure zipper is still parallel and evenly spaced. Sew opposite end with 3/8" seam allowance.

  6. If you have long zipper tape, don't make the rookie move and sew your zipper pull on the outside of the bag!
  7. Trim excess zipper tape off both ends.
  8. For bonus points, consider adding pull loops to the zipper ends. Grosgrain ribbon or excess zipper tape work great. Make sure your loops are sewn INSIDE the pouch!
