School Party - Satchels



Alright, so they're more popularly known as messenger bags but I grew up calling them satchels. Unlike traditional satchels, however, these aren't leather. They also have no buckles because I was mass-producing them for kids - I wanted to save time and wasn't convinced that kids were going to actually use the buckles. 

There is absolutely nothing original or creative about the basic design of satchels. Everyone is making them. They're rectangular pouches with narrow gussets and a flap that overhangs the front. Or, instead of gussets, they might have pinched corners. They have long straps that cross diagonally on the body to suspend the bag. Sometimes they have pockets and buckles. Whatever the variation, they are fun to carry, easy to make because they are rectangles and can be floppy and therefore don't require interfacing.

I made my satchels as goodie bags for Emily's party. Guests often decorate goodie bags, right? So we decided they should also decorate these satchels. The fabric for the front flaps are from the Color Me line sold in many stores. Rather than plain canvas satchels for the kids to draw random art on (also a nice possibility, but maybe for older kids), these fabrics have little printed motifs so all the kids need to do is color.

The Color Me fabrics are very thin - lighter weight even than quilting cotton so I had to interface them with fusible craft-weight interfacing to make them sturdy enough for the kids to color on. Fortunately that was the only part of the bag that needed stabilizing - the other fabrics are duck cloth and canvas for the outer layer, and twill for the inner layer. Very robust, overall.

The strap is nylon webbing. It's adjustable with a plastic slide, so the kids can wear the bag in whatever way and at whatever height they like.

You can find messenger bag tutorials everywhere on the internet, so I'm not going to do a step-by-step. I don't have a pattern because, for heaven's sake, it's all rectangles. You can have my cutting plan, though:

Click on the diagram above to download the instruction sheet. All the dimensions include seam allowances, and wherever you see rounded corners, just cut the rectangles to size and round off their corners, okay? I repeat, I DO NOT HAVE A PATTERN for the rounded corners. 

Here are some behind-the-scenes photos.

Working with just the outer fabric(s) layer, the first thing I did was to sew the flap to the back of the bag to make a continuous flap+top+back piece. Then I sewed one edge of the gusset to the front of the bag, and then the other edge of the gusset to the back of the bag.

Here is a close-up shot of how I attached the gusset around the rounded corners. This is the wrong side

and this is the right side.

I now had a complete bag, made out of the outer fabric(s).

Then I made the lining of the bag in exactly the same way. So now I had two bags - one in outer fabrics, and one in lining fabric. 

I turned the outer bag right side out

and fitted it into the lining (which was still wrong-side-out).

Then I sewed all around the free/unattached edges to attach the two bag layers to each other. I left an opening in the lining to turn everything right side out eventually, though. Here is an overexposed shot showing how I sewed that funny corner where the gusset intersects with the top+flap of the bag.

And here is that corner again, with lurid red thread showing the stitching line.

Then I snipped that corner, turned the entire bag right side out through the opening in the lining and top-stitched all around the edge of the bag.

The completed bag, inside out:

Then I made the strap system. If you want to further simplify it, omit the buckles. Just make a strap of a fixed length and sew both ends to the corresponding sides of the bag. For clarity, I sewed on a strip of fabric to distinguish the right side of the strap from the wrong side.

The short 4" piece of strap goes with the rectangular loop buckle and the long 45" piece of strap goes with the one-bar slide buckle.

This is how the loop-and-short-strap are attached to the side of the bag. I tucked the fraying edges of the strap between the webbing and the gusset.

This is how the slide buckle and the long strap go together. Sew the strap around the middle bar of the buckle.

Then slide the free end of that long strap through the loop buckle and thread it through its own slide buckle

and sew that free end to the other side of the bag gusset.

This is what the strap-and-buckle system looks like.

And this is what the inside of the bag looks like.

And then I made thirteen more, one of which was sized down a little (and with a narrower strap), for Kate.

These other thirteen all have plain straps. I trimmed just that one fancy strap for Emily, being the birthday girl. I'd have liked to trim them all because it's such a pretty detail, but I didn't want to take the extra time. Actually, if I weren't mass-producing them, I'd have done them quite differently, and added piping and more rugged top-stitching and front buckles and inner pockets and outer pockets for iPhones and water bottles and hidden panels and whatnot. But for fourteen, I went with classic and simple. 

At the party, the guests were provided with fabric markers

and everyone picked a bag and colored away. Even the grandma and moms (and a dad) helped.

Here are some of the decorated bags. I wish we had gotten photos of the striped bags - they were particularly spectacular.



The girls use them to cart around their art supplies and coloring books, and they love how the diagonal strap leaves their hands free!


As a result of all the bulk-sewing, I have two bags to put in the shop


These are both in the versatile and classic polka-dot design, which, if you wanted, you could transform into flowers by drawing petals around some of the circles. All you need is fabric markers! 


So if anyone wants a limited edition kid-sized decorate-able messenger bag, but doesn't want to make them, you can now buy them! Not quite in time for the start of school, but never to early for holiday shopping, right?

  1. How fantastic! A personalized treasure (holder) for each guest... wow!! That's more my idea of a great party than fancy decorations (although I would never have gone to all that work! ;) ) You rock, girl!

  2. And I thought *I* was nuts for sewing the goody bags for my daughter's 7th birthday! Ours were simple rectangular muslin tote bags with a twill tape shoulder strap. No gussets, no flaps, no interfacing, no lining, no slides or buckles. :) (The flowers-to-color are cute, but I assure you, kids this age are very happy to do their own artwork. In fact, my daughter prefers it; she considers coloring a bit babyish.) The birthday girl got a special strap in my house too, though! She picked out a fancy brocade trim to use for hers.

  16. What a terrific party gift!! I once made custom pencil cases during one of my daughter's parties. The kids were old enough to entertain themselves so I had them choose their fabrics and stayed in my sewing room making them the whole time. By the time the party was over, they had their gifts, and I still had my sanity.

  17. I stumbled across your site doing a search for messenger bag patterns to make for my husband for Christmas. Thank you for this pattern! I didn't even use your exact measurements, but customized them to get a size I wanted. Following your basic construction techniques, I added exterior and interior pockets to make it useful for a commuter. I've now been poking around your site and am so impressed with all the great ideas. Thank you!

  18. Brilliant instructions.....had sort of worked out a pattern myself but good to see that I was on the right track. Am going to add piping and pockets too. Loved the idea of using fabric pens to customize each bag. Thank you
