DIY Envelope Cushion Cover

An envelope-backed cushion cover is a great beginner project to have a go at if you’re new to sewing and a quick and easy solution to brighten up your home or in my case, the garden.


Cushion 18 inch x 18 inch (45cm x 45cm)
Fabric measuring 19 inches wide and 44 inches long
Sewing Machine
Measuring tape

I found this fabric at the Fabric Outlet in Newbridge for €5 a metre. They have an incredible selection and you can’t go wrong at that price. I thought the black and green would work really well in the garden and I needed new cushions for my outdoor sofas.

First measure up and cut your fabric. I don’t have a sewing room, or a sewing table for that matter, so everytime I sew I use the kitchen table. I lay out the fabric and measured up.

For the width, add half an inch for a seam allowance, so 18 inches + 1 inch is 19 inches.

For the length, double your cushion width [18 + 18 = 36 inches] and add 8 inches to allow the evenlope to overlap [4 inches each end]. Then transfer the measurements to your fabric and cut to size. If you are using patterned fabric, make sure you are cutting pieces where the design will be prominant to the front.

At the two short ends of your fabric create a double hem as these will be the edges of your envelope opening. Fold the fabric over by half an inch and press, and then fold the fabric over the previous fold by another half inch, press, pin and tack in place.

Use a sewing machine set to straight stitch to sew the hems on the right side of the fabric. I stitched two lines to secure the hem. I’m not particularly good at sewing straight lines, so hopefully nobody will look to closely at them.

Next fold your fabric in half and mark the centre. Then measure out 4 inches from the centre, mark and fold one end (left side) into this marked point.

Then measure 4 inches from the centre point again and fold the right side in to meet this point. Your hems should overlap, one over the other with 4 inches between them. This creates your envelope opening. Pin the hems down so they don’t move when you sew the cushion edges.

Once you have your fabric pinned in place, it is time to sew. The beauty of this project is you only have two sides to sew. Leave a quater inch seam allowance along each open side you are sewing. Once both sides are stitched together, use a scissors to snip off the corners.

Give your cover a press with an iron, then turn your cushion right side out, pushing a closed pair of scissors into the corners to get a crisp point.

All that is left to do is fill your new cover with the cushion filler and style your cushions to your hearts content. This is a simple and inexpensive way to update your decor with minimal sewing skills required.
