Now, use the same measurement (2″ for this example) and draw dots to mark two inches from the neckline. Since it is curved, this will help us draw an even line for the bottom edge of the facing.
Lots of dots will make it easier!
Connect all the dots to complete your pattern piece.
Repeat for the front neckline and cut out your pieces. I like to interface the facings for a little more stability. So do that if you want also. Lay out the pieces how you will sew them together.
Then pin and sew.
Press the seams open.
And serge (or zig-zag) the bottom edge.
Now pin your facing to the bodice neckline with right sides together and sew it on.
Sew it on.
Then clip the seam allowance or use pinking shears (I recommend ginghers). Clipping the seam will allow your neckline to curve without seam allowance pulling it weird ways.
That’s it! You’re done! Doesn’t it look nice?
