Sewing 101: Darts

Let’s all enjoy (and try not to laugh) at my little dart drawings here. They are meant to demonstrate the two basic types of darts. The basic dart on a pattern will be vertical darts. The other type of dart is a horizontal dart, darts like this shape the side of the bust. Darts on a pattern are typically triangular shape and they have a dotted line through the middle which is where the fold will be. the solid lines are the lines where you will sew. Confused? let’s walk through one shall we?

So here we have a pattern with a dart in it. This is a self drafted bodice piece with a dart. Then next to is is the fabric piece cut out.

To sew the dart first you have to mark it. You can do this a lot of ways drawing it right on to the fabric, or marking it with pins. Here is the way I handle darts which I find the easiest way. Start by lining the pattern up with the fabric piece. then with two pins mark both sides of the solid line.

Then with the right sides of the fabric facing each other fold the fabric so the pins meet each other. Then you can remove one pin and simply pin both sides together with one pin marking the spot.

Then with the fabric folded and the pin marking the sewing line of the dart…

Fold the pattern along the fold line and match it up with the fold in the fabric. Then use a pin to mark the top of the dart. You can see right now how the sew line angles from the bottom up to the top marking.

So now you should have the bottom and top of the dart marked. This will have the wrong side of the fabric facing up.

Now you will sew from the bottom point and angle up towards the top point. The stitch should smoothly run off the side of the fold. The important thing here is to keep the angle narrow and smooth. That will help it to lay the best. I usually back stitch at the point, depending on the fabric you can have a better result if you just run the stitch off the edge and then tie the threads to secure at the point.

So next if you are ironing the dart there are two ways of doing it. Using a tailors ham. (which is basically a small ironing ball that looks like a ham) or you can use the edge of the ironing board. You just need a curved edge to iron the new shape the dart.

Start with you basic bodice piece.

Then decide where you want the dart to be, and how high you want the dart to be. Then measure over and up to create a square.

Cut the square out. Then you will retrace the bodice piece. Angle the square piece away from the bodice so there is a triangle being formed in the blank spot. Then trace the rest of the outline of the bodice.

Mark the lines of the dart and you have a new bodice pattern piece with a dart.
You can apply the same idea to a skirt piece as well. (I will show you a dress with darts on Friday)

I hope this helped darts seem more friendly!
