First, gather all your materials and tools to get started.

Next, grab your measuring tape and measure the dimensions of your pillow.

Figure out the length and width of the pillow case and mark them on your fabric. You will also need to leave room for the overlaps, as well as the seam allowance. Once you figure out the math, simply make the markings on the fabric using tailor’s chalk.

Grab a pair of cloth scissors and cut out the fabric accordingly.

Fold an inch wide strip of cloth twice to use as hems and tag them in place with sewing pins. You can also iron the folds if you want neater and more defined seams.

Sew the hem on both sides.

Now repeat this for the overlap flap, as well. Fold a 4-inch wide strip of cloth and use sewing pins to secure it.

Next fold the fabric in half and align the ends. Once again, use sewing pins to secure the ends in place and then sew along the top and bottom of the pillow case. You can back stitch all through to really secure your stitches, especially around the corners.

Next, turn the fabric inside out. The wrong side of the fabric will be facing up, with the flap on the out as well, and the right side is facing in.

Now, use sewing pins to mark and tag your guide for the seam allowance and then just sew the two remaining sides.

Turn the fabric inside out, with the printed side facing out. Use your fingers to poke the corners out.

Finally, just insert the pillow into your pillow case and hide the edge under the flap. Your pillowcase is ready!
