There are tons of advice on sewing the perfect dart and I think it is mostly up to personal preferences. But I want to share my preferred method for sewing darts that is also super quick – with minimal marking and prep work. This method works best for straight darts, for curved ones I often have to rely on some kind of line marking.
Instead of using tracing paper or thread tacks I just mark the darts using an awl and a pair of scissors. First step is to punch a hole at the end(s) of the dart.
Then make holes on both sides of the dart, somewhere in the middle.
If you make a single straight dart also clip the ends with a scissor. This is all the marking you need!
This is how it should look like. You will use the holes as a guide and sew outside them. [I accentuated the holes in Photoshop so that they would show up in the photo, they are more discreet in real life]
Fold the dart in the middle and put pins in the corresponding notches (holes). You will not sew over the needles, they are just a guide and will be removed during the sewing process. I
This part requires a little practice and you need to use some eye balling here and aim for an even diagonal line. I like to make the stitch length shorter when I’m approaching the end and then I just sew a few small stitches and let them catch the fold of the fabric. You can also do a tiny pivot with the needle to sew the last few stitches. I never ever back stitch as it will make the dart ends bulky. The seam ends just below the lower hole.
Instead I do three knots at the end. That will suffice.
Now a little pressing and then you’re done! This dart may not be flawless since I used an vintage bed linen that is so firmly woven that it almost repels the needle. But the dart looks good enough in my book anyway!
