Envelope Back Cushion Cover

Envelope back cushion cover

This envelope back cushion cover tutorial was written by Julia York. 

Cushions can revamp your living room or bedroom, adding a touch of colour or pattern.  This envelope back cushion tutorial is ideal for beginners as it doesn’t require sewing zips.  So sew your zip free cushion cover now.


You will need

Beginner home sewing projects

A cushion insert whichyou can find in stores like Dunelm or The Range as well as many online stores. The cushion insert I’m using is an easily obtainable 40cm by 40cm.

Fabric – enough to cut one piece the same size as the cushion insert, plus 1cm for the seam allowances.  (So, for a 40cm by 40cm cushion insert you want a piece of fabric 42cm by 42cm.)

Choice of fabrics for cushions

Fabric enough to cut two back pieces each 42cm by 35cm. (Fabric used for the back doesn’t have to be same as the fabric used for the front – mix them up for a bit of contrast if you like.)

Scissors or rotary cutter and board

Matching thread

tape measure


Fabric Notes: I’m using home decor weight fabric for this project but medium/quilt weight fabric also makes a very nice cushion cover.  Be bold and choose a beautiful combination of colours and prints for your cushion covers.

To make your envelope cushion cover

Cut one piece of fabric 42cm by 42cm (this will help keep the cushion fairly plump looking. Cut two back pieces 42cm by 35cm.

Hem the back pieces – Take one of the back pieces and fold one of the 42cm edges over by 1cm.  Iron this into place.

Use a sewing guage

Turn it over another 1 cm and iron that down to make your double folded hem.  Pin this down if it helps to keep everything in place. 

Double fold hem

Take this to your sewing machine and sew down the edge of your folded seam.

Machine sewing a cushion cover

Repeat this with the other back piece.  Remembering that if your fabric has a one way/directional pattern you need to consider this, as you will want to have the pattern all the facing the same way.

Easy home sewing projects

Place the front piece face up on your work surface.  Lay one back piece right side facing down onto the front piece, aligning the top edge and the bottom edge. The un-hemmed side edge should line up with the outer edge of the cushion front.

Take the second back piece and place it right side facing down onto the other fabric pieces. Align the top and bottom edges as before.  The un-hemmed edge needs to line up with the outer edge of the cushion front.   

Things to sew for the home

There will be an overlap in the middle, with no ‘front piece’ fabric showing. (This forms the the ‘envelope’)

Pin this into position to hold everything in place.

Take this to the sewing machine and sew all the way around the ‘square’, using a 1cm seam allowance.   Move any pins out of the way so that you don’t break your needle as you sew. 

Fasten off any trailing threads so there’s nothing likely to come undone at any point in your soon-to-be cushions life.

Clip corners

Trim fabric away from the corners to reduce bulk and give give you nice corners when you turn your new cover inside out. 

Turn the cover inside out.

Give it a little press to tidy it up…
