Popular Uses For A Messenger Bag

A messenger bag is one of the most useful (and popular) bag types. A messenger bag like this one can be used pretty much everywhere and by everyone: as diaper bag, for trips and hikes, and for any errands you run, even for grocery shopping (easier to carry than a simple tote). Perfect as a gym bag, or as school bag, especially if you need space to tuck in a jacket too.

(While making it, also cut three pieces and make this free card holder pattern it only takes 5 minutes to sew one!)

MESSENGER BAG TUTORIAL

Let's see how you can make this diy messenger bag yourself.

Supplies You Need To Sew A Messenger Bag:

• exterior fabric and lining fabric: 1 yard each, (some fabric will be left)
• accent fabric for bag flap: half yard
• contrasting fabric for inner pockets: a little over fat quarter (or use exterior fabric)
• stiff fusible vowen interfacing for straps: 43" by 3" for strap
• fusible fleece: 41" by 45" (Pellon Fusible Fleece has 45" bolt width. Check out yours.)

How To Save On Fabric?

Instead of using contrasting fabric for pockets, feel free to cut them from main and lining fabric - it will be enough left if you've got one whole yard of each, exterior and lining fabric.

Of course, you'll get away using less fabric than stated here if you play around with the placing, but do mind if your print is directional. (I've drafted the fabric placement image to take into account the directional prints too!) Also, if you use a lower variety of prints, less fabric will be required.

TIPS to Use this diy messenger bag pattern:

Please note: bag exterior and bag lining pieces are NOT exactly the same measurements!! This will make your sewing project super neat, you'll soon see how.

As you will also have noticed, the fusible fleece pieces are just a bit smaller than the exterior to prevent bulk when sewing. Since we're using a ½ inch seam allowance, measure accordingly.

Also, the pocket will be folded in half, hence the measurements of the fusible fleece do not match. Just in case you were asking yourself why the discrepancy.

Cutting Template For Diy Messenger Bag

This cutting template will make your project even easier. I tend to forget to cut a piece or two if I only have a list to resort to - so, in addition to the cutting list above, here's an image for us, visual learners 🙂

Please click on the image to enlarge. It is meant as a visual aid for cutting, you'll still need to measure your pieces on the cutting table.

MESSENGER BAG TUTORIAL

Let's start.

1) Cut your fabric and fusible fleece as per cutting instructions above.

How To Make a Rounded Flap

2) Using a cup or another round object of approximately 2 ½ inch in diameter, round the bottom corners on the flap piece, and all 4 pieces of the bag body bottom (4 pieces - 2 lining, 2 exterior). You can round the corners before applying fusible fleece, or after - whichever you prefer.

3) First, we'll stitch the flap: place the 2 Bag Flap pieces on a flat surface, right sides together.

4) Stitch, then notch the seam allowance at the 2 rounded corners to make turning a breeze. Take care not to cut into stitches. (I wanted to be on the safe side and made sure to stop cutting approximately ⅛" away from the seam.) Then turn right side out and press.

5) Topstitch along all three finished edges.

6) Flap finished, set aside for now.

How to Make A Messenger Bag STRAP

7) Let's make the bag strap now. It will be quite wide, 3 inches finished width. I opted for a fixed length of 43" which I find ideal for a bag of these proportions, for men too. You can make adjustable straps if you want a crossbody version - adjustable strap tutorial HERE:

First, apply fusible fleece to one part of the strap fabric, and apply stiff woven interfacing to the other part. This is what I do when I want to make very stable bag straps.

8) Then stitch the two stripes right sides together, using a ½ inch seam allowance. Make sure to leave one short end open for turning.

9) Using a bodkin or a safety pin, turn the strap right side out and topstitch along both long edges. Bonus tip: I always use a longer stitch length when topstitching. This way, the stitching looks neat. Here, I may have gone a bit overboard, using a stitch length of 4, but it turned out great!

How To Make Extra Stiff Straps On Messenger Bags

Bonus tip: for an extra sturdy messenger bag strap, feel free to add an additional layer of cotton webbing on top of it - that is, if you have a heavy-duty sewing machine (I use this sewing machine for bag making) that will easily sew through all the layers of fabric, interfacing, and webbing.

The cotton webbing should be narrower than 3", and stitched to the very center of the strap. Check out my tutorial on sewing double layer bag straps.

How To Make Pockets For the Messenger Bag

10) POCKETS: Now it's time to make and attach the inner slip pockets. Take the two pocket pieces, apply fusible fleece - each fabric piece will only be half-covered by fusible fleece, because we're folding the fabric. Fold fabric right sides together:

11)  Stitch your pockets, making sure to leave a hole for turning on each piece. The turn right side out and press. The turning hole will remain open until a later step.

12) You'll sew the pockets onto one of the Bag LINING pieces. But first, place the small pocket on the large pocket and topstitch around the sides and bottom of the small pocket. This will also close the turning hole on the small pocket.  I chose to have the phone pocket on one side, 2 inch away from the top and left edge. You can center it, or add more pockets if you want to.  

13) Step 2: attach the large pocket onto the Bag Lining, stitching at approximately ⅛" away from the pocket edge This will also close the turning hole on the large pocket.

How To Assemble Bag Lining and Bag Exterior

14) Here are the 2 sets of pieces you'll need to assemble bag lining and bag exterior: two bag base pieces and the gusset piece.

15) So, we'll sew the Bag Lining first:

1. You'll need 2 bag lining pieces and the gusset piece for lining.
2. Pin or use sewing clips to align one lining piece of 17 by 13 with the gusset piece.
3. Notch the seam allowance of the gusset piece at corners to make a neat edge. Way easier to sew! Now stitch.
4. Same way, attach the other lining piece to the other side of the gusset piece. Make sure to leave a 5 or 6" opening at the bottom (see the spot marked by sewing clips in image No 4?)

Bag lining.

15) Proceed the same way to sew the bag exterior. Notice that the lining is shorter by half an inch? This will make sure the lining 'sits' nicely in the bag when stitched together. No wrinkles - you're welcome!

Final Assembly Of the Messenger Bag

16) Take the bag exterior piece. Turn it right side out. Use sewing clips to attach the strap (make sure it's not twisted!) and the flap onto the exterior. I suggest you baste them to fix the position. (Basting is a huge help, especially if you haven't made a lot of bags yet!)

17) Then fold the exterior with the strap and flap and gently maneuver it into the bag lining piece. Align the raw edges. Because the lining is a bit shorter, this will compensate for the thick interfacing. Be patient. There should be no puckers, and the side seams should be aligned. I prefer to use sewing clips - they make matching the raw edges so much easier!

IMPORTANT: Now the POCKETS (those sewn into the LINING) should be on the SAME side as the bag flap! 
So, are the pockets touching the Bag Flap? Good, continue!

18) Stitch all the way around the top of the bag. Then turn it right side out. Then stitch the turning hole closed.

19) Press well and topstitch around the top edge. This will make your bag look so much nicer!

20) Bury the thread ends when topstitching. Here's a popular how-to that can help you with neat seam finishing:
