Are you sewing darts the right way?
I don’t really believe in right and wrong in sewing – if it gets the job done, I’m all for it. But in sewing darts there is … a better way to do it! And if you experience always getting this small bubble underneath the darts you sew, like on the picture here, you are doing it the not-right way…
Learn to sew darts the better way..
Darts are one of the things that can really be a challenge when you start sewing clothes. They are marked on the pattern as triangles to sew away, but when you sew them, you get a small fold or bubble just where the dart ends. Which is really, really annoying.
The reason why the bubble is there, is because the fabric doesn’t fit the shape of your body and that there is too much or too little fabric right where the dart ends. To understand why, let’s have a look at the theory behind sewing darts.
What are darts in sewing?
Darts are – to put it short – triangles in the fabric, which you sew closed to give the flat two-dimensional fabric, three-dimensional curves that’ll match the curves on your body.
To illustrate, have a look at the drawing here. The big blue square represents a skirt, and the grey triangles are the darts we sew closed, to make the fabric take shape.
The darts are marked here and on your pattern as triangles.
But. Your body doesn’t have sharp triangles. It has curves. And that is why you should also sew the darts as curves. We’ll get back to that in a moment.
First you need to pin the dart. Place the notches (from the end of the dart legs in the pattern) on top of each other and let the fold of the fabric go until the pin you placed when you marked the tip of the dart.
If you want to, you can now use chalk to draw a line from the notch to the tip of the dart (the blue pin in the picture).
How to sew darts
Now. When you are sewing darts DO NOT follow that straight line (that would create a triangle, which won’t match the curves on your body). Instead you want to sew in a soft curve from the notch to the fold about 1 cm (3/8″) above the tip of the dart, then continue right at the fold for the final stretch. See how in the picture below.
It does sometimes take some practice to get the curve just right. This is where your remnant box comes in. Grab a bunch of remnants and sew maybe 10 darts to get the feeling for the right curve. It’s always a good idea to practice on scraps when learning new techniques, anyway.
How to press darts
Once you have stitched the dart, it’s time to press it into shape. First you want to press the dart flat from both sides, as it’s sewn, to set the stitches. Then place the dart on the matching curve on a pressing ham (or a tightly rolled up towel, if you don’t have a ham).
I like to press from the right side first. Let the dart cool of completely before you remove it.
