Tutorial: MacBook Air cover

We have a gorgeous bolt of Robert Kaufman’s Railroad Denim in the shop and a steady stream of ideas for it. Sturdy yet lightweight, modern yet classic – there is no end to the possibilities for this fabric! It’s also extra wide, so even a little goes a long way. This MacBook Air cover used just a fat quarter of Railroad Denim! Plus, the lovely indigo colour pairs excellently with so many fun lining fabrics. Now on to the tutorial!


Supplies list

FQ Railroad Denim – Medium Stripe in Indigo by Robert Kaufman (Please note this fabric is 54″ wide so the FQs are bigger. If you choose a 44″ wide fabric instead you’ll need .5m)
.5m lining fabric – medium weight quilting cotton. I used Sun Print – Feathers in Magenta by Alison Glass.
Craft size wadding (or two offcuts measuring 24″ x 14″ / 61cm x 36cm)
1 package of 3/4″ wide sew-on velcro (you’ll need approx 8 inches so if you have a scrap piece that’s fine too). I used black velcro.
Coordinating thread

Cut your materials

Cut one 25″ x 15″ piece each of your main fabric and lining fabric
Cut one 25″ x 15″ piece each of your main fabric and lining fabric
Cut two 12″ x 6″ pieces of your lining fabric
Cut two 24″ x 14″ pieces of wadding
Cut one 8″ piece of velcro



Round the corners of your flap

Fold your outer fabric and lining fabric in half lengthwise. Place a mug or bowl (the cup of coffee I was drinking worked fine for me!) at the outer corner and trace, then trim, to create round corners.


Repeat with your wadding. The rounded end of your materials is now the flap.


Baste your wadding to your lining

Double your wadding on your lining fabric and pin in place, leaving a 1/2″ seam allowance on all sides.


Set your machine to it’s longest stitch and baste the wadding in place about an inch from the edge. You’ll pull these stitches out later.


Attach your velcro

Centre the scratchy side of your velcro to the lining fabric, 1″ from the top of the flap. Pin.


Centre the soft side of your velcro to the main fabric, 3 3/4″ from the bottom of the bag. Pin.


Edge stitch the velcro in place on both pieces.


Attach your lining

Place your main fabric and lining fabric right sides together and pin.


Sew all the way around with a 1/2 inch seam allowance, leaving about three inches open to turn.


Clip corners to reduce bulk.


Turn the bag right side out and press.

Sew your pocket

Pin your pocket pieces right sides together.


Stitch all the way around with a quarter inch seam allowance. Leave about two inches gap for turning the pocket right side out.


Carefully clip your corners to reduce bulk


Turn your pocket inside out and use a point turner or knitting needle to gently push out the points.




Your finished pocket will look like this!


Attach your pocket

Centre your pocket on the right side of your main fabric, 6 1/2″ from the top of the flap. Make sure the side of the pocket that you left unstitched is toward the bottom of the bag. Pin in place.


Edge stitch around the sides and bottom of the pocket to secure, closing the unstitched edge of your pocket in the process. The top of your pocket is on the flap side.


Measure 3.5″ inches from one side of the pocket and stitch through all of the layers to create an iPhone pocket, if you want one!


Gently remove the basting stitches that were holding your wadding in place and give your bag a press.


Top stitch 1/4 inch from the edge of the bottom edge of your bag.


Fold the bottom of your bag up 9 1/2″ inches. Double check everything fits as it should – your velcro lines up and your MacBook Air fits! Pin.


Start at the bottom left corner of your bag (when it is facing you) and top stitch 1/4 inch from the edge, around the flap and down the right side. Reverse over the places where your bag meets the flap to reinforce.


You’re finished!


I did try this one other way, with the pocket inside the flap and fusible fleece rather than wadding, before I decided on the version you’re seeing in the tutorial. This uses Feathers in Fluorescent. Also a fabulous combination!


Now your computer is ready to travel!
