Step by Step Envelope Pillow Case

So, let’s get started on the exciting DIY envelope pillow case step by step!

Step 1: Measure Pillow Form

Start by measuring your pillow form to ensure the cover fits perfectly. In this example, I used an 18″ square pillow form. Measure from seam to seam on both sides and top to bottom.

Step 2: Cut Fabric

To determine the size of your fabric, double the width of your pillow form and add 5 inches. Cut a single piece of fabric using these measurements. For example, if your pillow form is 18″ wide, cut the fabric to be 41″ wide and the same length as your pillow form.

Step 3: Prevent Fabric From Fraying

To prevent fraying, sew a zigzag stitch or serge along the long edges of the fabric.

Step 4: Iron Hems

How much material is needed for a envelope pillow cover?

To figure out the amount of material required for an envelope pillow cover, you’ll need to measure the width and length of your pillow form. Double the width, add 5 inches, and keep the length the same as your pillow form. For example, if your pillow form is 18″ x 18″, you would cut a piece of fabric that is 41″ x 18″.

Can I use any fabric to make the envelope pillow cover?

Yes, you can use a variety of fabrics for your envelope pillow cover. Choose a fabric that complements your decor and is durable enough for regular use. Cotton and linen fabrics are popular choices for their comfort and versatility.

 Do I need advanced sewing skills to make this pillow cover?

No, this tutorial is designed for beginners. Basic sewing skills are sufficient, and the step-by-step instructions guide you through each stage of the process. It’s an excellent project for those looking to enhance their sewing abilities.

How do I clean the envelope pillow cover?

Simply remove the pillow form through the back flap and launder the cover according to the fabric’s care instructions.

Is it necessary to prewash the fabric before making the pillow cover?

While it’s not mandatory, prewashing the fabric is recommended to prevent any potential shrinkage after making the pillow cover.

Can I hand-sew the pillow cover instead of using a sewing machine?

Yes, you can hand-sew the pillow cover if you don’t have access to a sewing machine. Remember that a machine saves time and provides a more secure and polished finish.


Now, you’ve just created a beautiful envelope pillow case with a convenient back flap. Now, you can easily remove the pillow form for washing whenever needed.
