I am going to look at, and demonstrate the fashion sewing technique of sewing vents.

In particular, we shall look at the process of completing a vent (you may also know it as a split) in a skirt.

Vents, no matter the garment type, are much the same, so if you can master this fashion sewing technique, then you really shouldn’t have any problems completing them on other sewing projects.

So What Is A Vent?


Vents are easily identifiable! They are found as an extension to the seam allowance on a sewing pattern piece.

Vents are created within a garment and not only create decorative style, but are used to ease movement. For example, a vent in our skirt enables us to walk more readily.

Vents are more commonly found to the rear and in the back of a garment but in the case of our skirt, can be found elsewhere, such as the front or sides.

Positioning vents, although used mainly for practical purposes, do take into consideration the style and design of a garment.

As I mentioned, I’ve filmed a tutorial video demonstrating the sewing of a vent in a skirt which you’ll find below. Please take your time to view and if you have any questions thereafter, please feel free to drop me a line.

A Little More Instruction


1 – Neaten the raw edges of your fabric.

2 – Using a straight stitch, sew lengthwise along the neatened edge of the extension to the wrong side, about 1cm – 3/8inch.

3 – With the right sides together, sew the back seam using a regular stitch length. Sew as far as the sewing pattern indicates but not the extension. Back Stitch.

4 – Continue to sew the extension to the hemline, using a larger stitch on your sewing machine. Do not back stitch. This will help to give the vent a crisp and sharp finish.

5 – Sew the width of the vent from the sewing pattern marking to the end. Back stitch.

6 – Snip into the corner of the vent at the seam allowance but DO NOT cut the stitching.

7 – Press the seam open including pressing the stitched vent area. Remove the temporary large stitching.

8 – Turn your work to the right side and secure the extension with a row of top stitching. The vent is now complete.

So give it a try, and you’ll realise it’s not as hard as it sometimes looks.
