Tasche mit weiter Öffnung nähen: Schritt-für-Schritt Anleitung

Sewing a bag with a wide opening is a lovely project for sewing beginners. Not only because the little bag is quick and easy to sew - it is also super practical!


For a long time, I have been looking for a method to sew a bag with a large opening. I love cosmetic bags where the zipper is nicely encased and looks neat. How to encase a zipper, I made a detailed tutorial on that some time ago.

By the way: Click here if you want to sew waaaay more cosmetic bags! :)

Quick & easy: Sewing a bag with a wide opening

sewing a bag with a wide opening

I really like it when you open a bag and can immediately inspect the contents. I found a truly great tutorial for such a little bag from the inspiring Anna of Noodlehead.

I have adapted the whole thing to my needs and put it into a short tutorial.

Small tip: My outer fabric, by the way, consists of many fabric scraps that I joined together with the quilt-as-you-go technique . A truly ingenious method to use up beautiful fabric scraps!

In my guide to sewing with fabric scraps I show you how this technique works.

What you need for sewing

  • 11 x 5 cm fabric for the zipper tab
  • approx. 35 cm zipper with slider* (you can use either a finished or a continuous zipper)
  • optional: beads* and decorative cord* for decoration
  • possibly ribbon or grosgrain ribbon for decoration (I ordered my beautiful measuring tape ribbon* online)
  • color-matching or contrasting sewing thread
  • fabric scissors
  • pins
  • rotary cutter
  • marking pen
  • patchwork ruler
  • cutting mat
  • iron and ironing board - for example, a practical DIY ironing board! ;)sewing a bag with a wide opening

Tutorial: Sewing a bag with a wide opening

Place the zipper flush against the upper edge of the first outer fabric piece.

If your zipper, like mine, has metal stops at the ends, they should be about 1.5 cm away from the side edge.

Place the first lining piece right-side down on the zipper and pin everything well.

Mark 3 cm before the end of the seam.

Sew up to the 3-centimeter mark.

Leave the needle in the fabric and guide the zipper away from the top edge downwards.

Now finish the seam and backstitch.

This is what it should look like now:

The zipper is between the lining and the outer fabric:

Mark 3 cm from the sides on the zipper start and end of the topstitch.

Topstitch the zipper with a longer straight stitch along the edge.

Fold the end of the zipper inward a little and pin it in place.

This way you avoid catching the zipper in the subsequent seam.
