How to add a zip to an item.
Step 1: Take the two sectons of fabric that need a zip (we will use a skirt as an example). And sew a whole seam from top to bottom connecting the two pieces of fabric.
Step 2: Using an iron press the seam open flat. Place your zip onto the fabric the correct way, and either pin or tack to secure.
Step 3: Using the zipper foot for your sewing machine sew carefully along the zip, you will have to open the zip as you go so you can move the slider out of the way.
Step 4: Turn the skirt over and take a seam ripper and carefully cut the original seam (that joins both fabrics). All done! How super simple was that?!
