1) Mark Your Darts
On the back of your fabric, mark the locations of the small circles along the dart, as indicated on the pattern piece. Try to keep these dots small. I usually stick a pin through the centre, then draw with a
2) Pin the Dots on the
Take a pin and push it through the two dots directly across from each other on either side of the dart. Best to use long pins if possible, depending on how wide the dart is. Do this for all dots.
In addition, put a pin through the dot at the top of the dart where the seam lines connect, only catching where you marked the dot. This will help you when you fold the dart.
3) Pinchy Pinchy!
At each pin, pinch the fabric so that the two dots on either side of the fabric are touching, pierced on the pin, as shown below. Make sure that you haven't twisted the fabric and that the pin is going straight through the fabric.
Then simply bring the pointy end of the pin through the fabric below the dot, with the head of the pin over the edge of the dart. Do this for all pinned dots.
Complete the fold along the dart, then lightly press the fold flat. Add more pins along the dart, if needed.
4) Double Double Toil and Trouble
Double check to ensure that the seam lines are lined up properly, otherwise it could cause toil and trouble (and seam rippers). Sometimes the fabric shifts when you bring the pin back through the fabric, so it's always good to check. To do this, push a pin through the seam line on one side of the fabric, and make sure it's coming out through the seam line on the other side.
If the seam lines do not line up perfectly, then adjust the fabric until it does. I usually find that if it does shift, it's only by a tiny amount.
5) Sew Sew Sew Your Dart (Gently Down the Seam-Line)
Now all that you need to do is sew the dart! Et voilà, a perfectly lined up seam line for a perfectly sewn dart! Well, if you manage to sew it straight, which is usually where I go wrong. Sorry, I haven't any tips to help you out with that!
