0 comment

This tutorial will show you how to make cushion covers in an envelope-style in 10 minutes and with just one simple piece of fabric. Have you got some tired cushions that are in desperate need of a make-over? New cushion covers are an inexpensive way to update your living room and to add a touch of color and warmth to a comfortable couch.

How to Make Cushion Covers

Envelope cushion covers are removable and have a slit at the back with an overlap of fabric. This makes them easy to get on and off your cushions when they need to be washed and best of all there are no zippers or buttons to sew.

Intermediate and advanced sewers will be able to make these cushion covers really really quickly. But I promise even if this is your first time sewing, you will be able to sew cushion covers in this envelope style with ease.

How to Make Cushion Covers – Supplies

Best Fabrics

You want to make your cushion covers in sturdy fabrics that can be washed. Choose decorator fabrics such as upholstery fabric, canvas, drill or duck or medium weight quilting cotton.

Fabrics such as velvet do look nice on your couch but won’t take as much wear and tear. So think about how much you will be using the cushion covers and whether they are just decorative.

I also like to choose fabrics that don’t squash easily. Linen looks modern and trendy but will get very creased if you plan on sitting on it every day.

Inserts for Cushion Covers

Cushion inserts are available from most homeware and haberdashery stores in a variety of sizes. They are nearly always white with a non-woven cover and stuffed with polyester stuffing. You may even just remove your old covers and reuse what you already have.

Discount stores are also a good source of cheap cushion inserts. If you find a cheap but ugly cushion you can use this how to make cushion covers tutorial to recover them.

This tutorial will show you how to make cushion covers for any sized square insert.

The Basic Supplies

Basic sewing supplies are needed such as rulers, scissors, pins, thread and of course your sewing machine.

How to Make Cushion Covers

Before you start, have a look at this graphic. This will help you visualize a little better the steps we are about to take. Not much to do is there! You will probably take the longest choosing and cutting your fabrics rather than sewing.

How to Make Cushion Covers

Measure the Insert

Measure your pillow insert’s dimensions. Make sure you are measuring around the curve of your pillow and not just the finished width.

Because we are learning how to make cushion covers that are square, the length and width will be the same. If yours is a little rectangular, the formulas below will still work – just do your maths carefully.

How to Make Cushion Covers by Measuring the Insert

Cut the Fabric

Cut your fabric in a rectangle with the following dimensions. Use a rotary cutter and mat if you have one to get nice straight edges.


  • Height – Add 1 inch (2.5cm) to the height for the seam allowance.
  • Width – Multiply the width x 2 (for the back and front) and then add 6 inches (15.2cm) for the overlap.

This will give a finished cushion cover the same size as your insert. If you like a really tight cover then reduce the height by 1 inch (2.5cm).

How to Make Cushion Covers – Sewing Instructions

Step 1: With your fabric WRONG side up, press over the shorter ends by 1/4 inch (6mm). Press them over again by 3/4 inch (2cm).

Step 2: Stitch across the hems with a sewing machine straight stitch.

Now if you got to this part and thought oh-no I don’t have a sewing machine, don’t worry. You can hand stitch these ends and the seams in later steps with a backstitch or a running stitch.

Step 3: With the fabric RIGHT sides together, fold in the left and right hemmed edges so they overlap by 4 inches (10cm). Try and get the overlap centered. Mine could have been a little more to the left.

You can double-check the width of the cover. It should be the same width as your insert.

Pin the overlap in place and pin the upper and lower raw edges.

Step 4: Stitch across the upper and lower raw edges with a 1/2 inch (12mm) seam allowance.

If you are using a fabric that frays you finish the seams with a zig-zag stitch or serger. This will help it last through multiple washes.

Step 5: Clip the corners. Turn your cushion cover the RIGHT way out and give it a good press on a setting suitable to your fabric.
