- Tape measure
Before you start:
If your fabric is washable, and if you might want to wash your cushion cover in the future, it’s a good idea to wash your fabric before you cut the fabric to size. This will take out any shrinkage, and ensure you’ll be able to get the cushion back into the cover! We’ve said you need a sewing machine, but you can of course sew your envelope cushion by hand if you prefer.
You’ll notice that the measurements in this tutorial are in inches. This is because our cushions in the shop are sized in inches, and also because our ace maker Mad, who helped us make this post, likes to work in inches herself. Please convert the measurements to centimetres before you start if it’s easier for you – just remember to stick to inches or centimetres throughout!
Cut a piece of fabric the right size for your cushion
Cut one length of fabric 18″ by 44″. Your piece of fabric doesn’t need to be more that 18″ wide for an 18″ cushion – our makers always cut a cushion the exact size of the cushion pad, for a nice plump fit.
Hem your fabric
Make double fold hems along both of the short sides of the fabric.
To do this, fold the fabric over half an inch, and then fold it over again. This keeps the raw edge tucked away out of sight.
Press the hem with an iron to fix it in place, and use pins as well. This will keep everything in position while you are sewing.
Sew the hem
Stitch the hems you’ve just made on the machine or by hand. Make your seam closer to the inside edge to make sure that you catch both folds of the fabric.
Fold it up
Lay your fabric on the table with the show fabric (the right side) upwards. Now fold each end of your fabric over by about 12″. Now the show fabric will be inside, and there will be an overlap of fabric.
Check before you sew!
You’ve cut your fabric 18″ wide, but measure your cushion cover before you sew to make sure it’s 18″ square.
measure, then adjust the amount of overlap if needed. Make sure the fold is level across the cushion too. Once you’re happy with your envelope cushion cover, pin it in place along the side seams.
Sew the side seams
Sew along both of the side seams of your envelope cushion cover. You’ll need a seam allowance of about 1/2″. That’s 1.5cm in new money!
Zig zag stitch (optional)
Most sewing machines will do a zig zag, and if yours does it’s a really good idea to do a zig zag stitch along the side seams. This will neaten the raw edges and help stop fraying, which is particularly important if you think you might want to wash your cushion cover!
Turn your cushion cover the right side out, taking care to push the corners out fully. Insert an 18″ cushion pad into the opening at the back.
Your 18″ cushion pad should fill your envelope cover fully, so make sure you push the cushion right into the corners of your cover. If you’re buying a pad, You can choose from hollowfibre or feather – it’s up to you – just check it’s the right size before you buy!
