Making pillows could not be easier! If you can sew a straight line on the sewing machine, you can make these! The first thing to do is to add 1" to the width and height of the measurement of the pillow insert. So for a 12" x 16" square pillow, cut two fabric pieces 13" x 17".
Buy a polyester zipper that is approximately 14" shorter, or you can sew the end to shorten....
Now lay the zipper face up lined up with the edge of the fabric and pin in place if you want to.
I always open the zipper before sewing all the way down so the footfeed will clear the zipper.
Now lay the fabric with inserted zipper on top of the other piece of fabric and stitch in place.
Finish sewing the other 3 edges leaving the zipper open a few inches so you can turn it right side out.
Turn inside out:
Now cut off the pesky tag on the pillow insert.
