Triangular bag :: a tutorial

Triangle bag :: a tutorial

You can't look past the Martin Margiela triangle bags on the net lately. I had seen this type of bags before, pre-Margiela, I mean, and a lot cheaper too. I liked the minimalism - they reminded me of Japanese bag folding, furoshiki. The ingenuity is striking - a good example of how to optimize under constraints (this is the economist in me speaking) or translated in sewing terms: how to make the largest bag possible given only a small piece of fabric.

Anyway, as I was trying to figure out how to make one of these, I found out you can do so in a couple of different ways (I figured out at least 3 different methods). It all boils down to basic geometry, combining shapes in one way or another. I made several and I find the method described below to be the easiest one. All it takes is a rectangular piece of fabric, some folding and basic sewing skills. And if you prepare your fabric by hemming it all the way around, you can make this bag in under 15 minutes. As fast, almost, as furoshiki folding, except that this one's permanent.

What you need:

Note: this bag can be finished in many different ways. I won't go into detail here, but you could add lining, pockets, add a longer strap, finish it off with boxed corners, etc. Just know that when you add something you'll need more fabric.

- a rectangular piece of fabric, where the length of the fabric equals three times the width. To give you an idea of the dimensions: a 50 cm x 150 cm piece of fabric results in a 65-70 cm wide bag (which is really big!) depending on how you finish the seams.
- sewing machine, thread, pins
- Iron

Instructions:

1. Hem the fabric all the way around.
2. Place the fabric in front of you, right side facing up, and start folding as shown in the pictures.
3. Pin the fabric together where it says 'sew' on the picture. Flip over and repeat on the other side.
4. Sew together both seams on the machine. Turn inside out. Press.
5. Handle: Join the tips by overlapping them and sew into place.
A nice detail: before joining the tips I slipped on a piece of leather - a detail I was really proud of. It's only while looking at the Margiela pictures, right now, as I was writing, that I noticed they did the exact same thing...


That's all there is to it! I hope you like this bag as much as I do...


Cheers,


Pascale

  6. Awesome! I reckon one could use a big scarf (pashmina??), then there is no need to hem the sides.
    Thanks for the tutorial.

  7. Pascale, thank you very much for revealing the mystery behind this very clever, economical bag.

    I think that I will have to try to make one ... I am already thinking about which fabric to use.

    Your posts are always terrific. I always pop by, even though I don't always leave a message.

  15. I'm fairly new at this. I had a question. When you line it do you make the lining the same way you made the outside of the purse? Or a tad bit smaller? Thank you for the great tutorial!

  16. for those of us still laboring under inches, I found a piece of fabric 15 inches long and 44 inches wide made a nice sized bag- a little smaller than a market bag, but perfect for a few quick purchases. I used bias binding instead of hemming. Thanks for the instruction!

    What kind of fabric do you use?

  20. @ Ine: I used linen - but any fabric could work. However, consider lining the bag when using a light weight fabric. Hope this helps
    @ Tracy: lining: I always make the lining the exact same size as the outside.

  24. Great tutorial. This bag is based on a Japanese bag called the Azuma bag. I make these with a slightly different method.

    I made a version from an old jeans, cut up one leg to get a piece of 30 by 90 cm (with the back pocket on it). Made a lining exaclty the same way (but left an opening for turning), sewed together at the top, turned, pressed, topstitched et voilà! Oh, I also added a zipper pocket using this tutorial http://www.craftpassion.com/2010/04/sewing-tutorial-internal-zipper-pocket-for-bag.html.

  32. Great bag - it brought back memories from when I used to make these almost identical style back in the 1970's.

  33. I loved this so much that I got right to work as soon as I saw it. I used a vintage linen tablecloth that I had been wondering what to do with. I was able to use most of the beautiful embroidery work. I added lining and pockets to the inside, making the pockets out of the left over embroidery work. Thanks for the tutorial!

  34. Aside from making boxed corners on hers, I think this woman pretty much stole your design and is calling it hers.

  38. I am going to try this with Guatemalan fabric that was handwoven, and let the width of the weft material govern the size.

  39. Very functional and the idea is great. I have dress fabrics I can use to try this.
