For example, you could choose a cotton or cotton-linen blend to make your pillow cover.
For example, if the pillow you are making will be 14 in (36 cm) long on the side that you want to add a zipper onto, then chose a zipper that is 10 in (25 cm) long.
For example, if you want to create a square-shaped pillow that is 16 by 16 in (41 by 41 cm), then you will need to a pillow form in these dimensions.
For example, if your pillow form measures 16 by 16 in (41 by 41 cm), then cut your fabric so that it is 15 by 15 in (38 by 38 cm).
If desired, you can insert a few pins to help keep the 2 pieces together. However, this may only be necessary if the fabric is slippery.
Only do this for 1 edge of the pillow and leave the other sides open for now. This will create the opening for your zipper.
Repeat this on both ends of the seam.
Be careful not to sew over any pins or you may damage your sewing machine. Cut the excess threads after you finish sewing the zipper in place.
Be careful not to cut through the stitches at the corners of the pillowcase.
You may need to adjust your zigzag stitch settings to ensure that the stitch will not be too wide.
Your zippered pillow cover is complete!
