Whether you're a seasoned seamstress or a beginner eager to dive into the world of sewing, this guide is designed to help you successfully create beautiful, custom pillow covers that perfectly complement your home decor.

The following list features the most common sizes available in pre-made pillow forms to help get you started:

  • 16×16 inches – This petite pillow size is ideal for use on smaller sofas or accent chairs. These versatile cushions effortlessly complement each other in multiples, and they make for perfect accent pieces when adorning a larger bed or couch, and can be coupled with larger pillows for a layered look.
  • 18×18 inches – The epitome of standard throw pillow size, this 18×18 inch cushion reigns supreme in popularity and versatility. Whether standing alone or paired with smaller or larger companions, it seamlessly adapts to the unique dimensions of the space you're decorating.
  • 20×20 inches – Step into the realm of larger throw pillow sizes with this 20×20 inch beauty. Tailored for grander sofas or beds, these pillows not only provide a luxurious aesthetic but also act as an anchor, harmonizing effortlessly with smaller throw pillows for a well-rounded look.
  • 24×24 inches – Experience the grandeur of oversized elegance with this 24×24 inch pillow, a statement piece crafted for sectionals or larger king-size beds. These lavish cushions are designed to complement the scale of larger furniture, adding a touch of opulence to your living spaces.

Once you get the hang of creating square throw pillows, you may wish to mix it up by creating other shapes and sizes: Lumbar (rectangular pillows), Bolsters, Circular, and even Free Form Shapes. 

So, gather your materials, thread your sewing machine, and let's have some creative fun!

Materials Needed:

  • Fabric of your choice
  • Matching thread
  • Invisible zipper
  • Pillow form
  • Sewing machine
  • Scissors
  • Pins
  • Iron

Step 1: Measure and Cut Fabric

Begin by measuring and cutting two identical squares or rectangles from your chosen fabric. Ensure the dimensions are equal to the size of your pillow form plus seam allowances. If you're making a 16x16 inch pillow, for example, cut two pieces each measuring 17x17 inches to account for a 1/2 inch seam allowance on all sides.

Step 2: Align and Pin

Place the fabric pieces right sides together, aligning the edges. Pin the fabric along three sides, leaving one side open for the zipper. This will be your pillow's opening.

Step 3: Install the Invisible Zipper

Position the zipper face down on the open side of the fabric. Pin it in place, making sure the zipper teeth align with the fabric edge. Using a zipper foot on your sewing machine, stitch the zipper in place on both sides, ensuring a clean and straight seam.

Step 4: Sew the Remaining Edges

With the zipper closed, sew the remaining three sides of the pillow, securing the fabric together. Make sure to backstitch at the beginning and end of each seam for added durability.

Step 5: Trim Excess Fabric

Trim any excess fabric from the corners and edges, taking care not to cut too close to the stitching. This will reduce bulk and help achieve crisp corners when the pillow is turned right side out.

Step 6: Turn Right Side Out

Carefully unzip the invisible zipper, then turn the pillow cover right side out through the open zipper. Use a blunt object to gently push out the corners for a cleaner, more defined shape.

Step 7: Insert the Pillow Form

If using a pillow form, insert it into the cover through the open zipper. For those opting to stuff the pillow, do so at this stage until you achieve the desired fullness.

Step 8: Zip and Finish

Zip up the invisible zipper, ensuring it glides smoothly and remains hidden. Finally, inspect your pillow cover for any loose threads or imperfections, and trim them for a polished, professional finish.

Congratulations! You've just crafted a beautiful knife-edge pillow cover with an invisible zipper closure—adding a touch of handmade elegance to your home decor. Now, let your creativity flourish as you experiment with different fabrics and patterns to tailor your pillows to suit any style or space.
