Learn how to sew a simple rectangle envelope cushion cover.
At the moment I’m spending a lot of time planning and making things for my future living room. I spend about 90% of my life in my rental’s living room (what’s going outside?), so it’s really important to me that my future living room is a comfortable, relaxing space.
As part of my planning, I’ve been in the process of making a few different cushions for my couch. After making a square tie closure cushion cover, I decided that I wanted to mix things up a little and make a rectangle cushion cover.
I had a look around on Pinterest for some rectangle cushion cover tutorials but a lot of them involved zippers and/or button holes. As a beginner seamstress, zippers and button holes make me scream in terror, so those tutorials were out. Eventually I found a tutorial for a square envelope cushion cover that looked easy enough. I took the basic idea and changed a few things in order to create a rectangle version.
This envelope cushion cover is the easiest cushion cover I’ve sewn in my entire life. It’s made by sewing just four lines of straight stitching. Which, in all honesty, makes it my dream cushion, because “a line of straight stitching” is about the extent of my sewing skills at the moment.
How to sew a rectangle envelope cushion cover
The dimensions below assume a rectangle cushion insert that measures 12″ x 24″. You can buy a 12″ x 24″ cushion insert here.
- A rectangle of fabric measuring 14″ x 26″. I use a rotary cutter to cut my fabric because it makes it easier to cut a straight line. In terms of fabric, any type will do – I used some cotton drop cloth I had leftover from my farmhouse pillow cases.
- A sewing machine, measuring tape, sewing pins, and fabric scissors.
- An iron.
To begin, flip your fabric over so that the backside is facing up.
At both ends of the rectangle, fold the fabric over to create a 1/2″ hem. Press the hems with your iron, then secure with pins. Using a basic straight stitch, sew a straight line along both hems in the spot indicated on the diagram below. As with all of my sewing projects, I recommend you start and finish each line of stitching by stitching forward for a few stitches, the stitching backwards, then stitching forwards again. This helps keep everything nice and secure.
Next, flip your fabric over so that the right side of the fabric is facing up. Mentally divide your fabric into rough thirds, as per the diagram.
(It was at this stage that I added my ‘Flower Market’ design to the cushion. To do this, I created a the design in Microsoft Word (because I’m clearly a graphic designer), printed it on to some iron on transfer paper, then ironed the design on to the middle third of the cushion cover.)
Fold the outer thirds (the left most third and the right most third) towards the middle, allowing one of the thirds to overlap the other. Pin everything in place.
With your fabric folded, sew a 1/2″ hem at both the top and the bottom of the cushion cover.
And that’s basically it. All that’s left to do is turn the cushion cover inside out (removing the pins as you go, unless you like to live dangerously) and pop your cushion insert inside.
