I love box pleats. They are one of my favorite things to add to my design simply because they are so classic. They give a wow factor to any garment and they are fairly simple to sew. The Rebel Girl Party Dress and the Alice Pleated Dress both feature inverted box pleats and I just love them. I thought I would write up a quick tutorial to show you how easy they are.
Sewing Tutorial: Box Pleats Made Easy
Box pleats can look scary if you have never done them, but they are actually a snap! I took the photos from our Box Pleat hack we did for the Rose Bubble shorts to show you how to do them.
First, transfer your pattern markings. I like to use a water-soluble fabric pen. Just be sure to test it on your fabric first.
Next, you want to line up your two outer lines and fold so they meet. On BSD patterns, these are the solid lines. The fold will be on the dotted line.
Then, baste on that solid line and you will end up with something like what you see above.
This is how it will look from the front.
Next, you want to press the pleat so that the fabric in the back is distributed equally on either side of the basting. This will actually put your dotted line right at the basting. The picture above shows both the right and the wrong side so you can see what it looks like.
You can then baste the top seam to keep the pleats in place when you sew. Leave the basting in until you sew your final seam. That way your feed dogs won't shift the fabric out of place as you sew.
That's it! Now you are a box pleat master! Now you can add them to everything!
