Messenger Bag with Flap – Tutorial

It’s been a while since I’ve shared a sewing tutorial. This one is easy and fun. I’ve made several messenger bags in the past couple of years as gifts for the children in my life. I recently wanted to make another one, but this boy was a little older, and I felt he could use a more grown up messenger bag – one with a flap and not a velcro or button closure. I took pictures along the way so I could share with you how I did it.Healthy Simplicity - Messenger Bag with Flap Tutorial

This bag takes a little less than two metres (yards) of fabric. If you buy a whole two yards you could always use the extra to make a crayon roll like I did. The interfacing is optional, but it will make the bag firmer.

Cutting the fabric is super easy if you have a self-healing mat and rotary cutter. Buying those two things years ago was one of the best sewing tool purchases I have ever made. Here’s how you need to cut your fabric…

Fabric

  • 6 – 12″ x 12″ (two for outside bag, two for lining and two for flap)
  • 6 – 12″ x 6″ (2 bottoms and four sides – bag and lining)
  • 2 – 12″ x 7″ (outside pocket)
  • 2 – 2″ x ? You will have to determine how long you want the strap to be.

Interfacing

  • 2 – 12″ x 12″
  • 3 – 12″ x 6″
  • 1 – 12″ x 7″
  • 1 – 2″ x ?

To be honest, I never cut my interfacing out first. I iron my fabric to it and once they’re stuck together I cut the interfacing out then.

Attach interfacing to one of the pocket pieces. Then with right sides facing sew the pieces together along a 12″ side. Turn the pieces wrong sides together, press the seam and topstitch it.

Take one of your square outside pieces with interfacing attached to it and sew the raw edge of the pocket to the bottom of this piece.

I put a piece of paper in so you can see where the pocket it is.

 

Now take one of the 12″ x 6″ pieces with interfacing attached (this will be the bottom of the bag) and sew it to the bottom of this piece.Healthy Simplicity - Messenger Bag with Flaps Tutorial
Next take another 12″ x 12″ piece with interfacing attached and sew it to the other side of the bottom piece.Healthy Simplicity - Messenger Bag with Flaps Tutorial
 Attach interfacing to two more of the 12″ x 6″ pieces and sew these on either side of the bottom piece.Healthy Simplicity - Messenger Bag with Flaps Tutorial
Sew each side edge up. You should now have a bag. Sew the lining in the same way except that it won’t have a pocket or the interfacing. Healthy Simplicity - Messenger Bag with Flaps Tutorial

Attach interfacing to one of your remaining two 12″ x 12″ pieces, and then sew them together right sides facing on three sides. Turn the flap right side out and press the seam flat.

Take the flap and line it up with the raw edge of the outside bag that does not have the pocket on it. Sew it in place.

Attach interfacing to one of your strap pieces. With right sides together sew the strap down both long sides. Turn it inside out and press it flat. Topstitch the two long sides.

Line the straps up with the raw edges on the sides and sew it in place.

Now this is the part that I always messed up, but if you follow these instructions you won’t! Turn the main bag inside out and the lining right side out. place the main bag inside the lining and sew all around the top edge leaving a 2-3 inch opening for turning.

Turn your bag right side out. Press the seam flat and topstitch all around the top edge.Healthy Simplicity - Messenger Bag with Flaps Tutorial

That’s it. You’ve done it! This size is great for an older child or even an adult.

Do you enjoy sewing bags? I love it.

  1. It turned out so cool! Thanks for posting this, because I’ve been thinking about sewing up a couple of new bags as a fun way to reuse t-shirts I love but don’t/can’t wear, and this will be very helpful when I get around to that.
