How to Sew Balanced Darts

Have you ever sewn darts that come out a touch bulky and unsightly, no matter how much you steam them into submission? This can be a problem when sewing thicker fabrics in particular. Vanessa here with a super simple couture dressmaking technique that will “balance” out the layers of fabric to get a beautifully smooth finish on your darts, even on the thickest of fabrics.

You can use this technique on any fitted garment made from medium to heavy-weight fabrics such as our Etta dress, jackets, skirts or trousers. It works by stitching a folded swatch of fabric to one side of your dart and pressing it in the opposite direction to “counter-balance” the centre line.

It feels like it shouldn’t work – adding fabric to make something less bulky? But it does!

Practise the technique on a sample first, then move onto your dress.

Cut a rectangle of fabric slightly longer and wider than the dart you want to work with. If you’re making a dress with lots of darts, like Etta, I’d use this technique for the most noticeable ones only - such as the bust and waist darts.

Fold the dart in half, right sides together, and pin the legs together. Slip half of the rectangle of fabric under the dart and pin all the layers together.

Stitch the dart legs together, catching the additional rectangle of fabric in your stitching too.

Press the layers of fabric flat, then press the fabric rectangle away from the stitching line. Trim away the excess fabric following the folded edge of the dart. Be careful not to cut through the dart itself!

Press the dart in one direction, and the extra fabric in the other. Turn over and press the dart lightly from the right side. It helps to use a press cloth and a rolled towel or tailor’s ham to get a smooth, shine-free finish.

Et voila! Slinky smooth, curvy darts that take your finish to a whole new level!

Confused about what just happened? Let me explain a bit more! You might have noticed that in past projects, when you’ve sewn darts in medium or heavy-weight fabric, they can create a small bulk of fabric in the direction towards which it’s pressed. This is down to an unbalanced distribution of the fabric’s thickness. You could cut the dart in half and press it open, but that’s messy and likely to split open! By stitching the same layers of fabric to the dart, and pressing them in the opposite direction, the thickness is “counter-balanced”. Clever, huh?

Give it a go next time you sew darts on bulky fabric!
