Keyhole neckline blouses are the epitome of easy-to-make elegance, a small detail that feminizes and embellishes any blouse.
Allow me to show you how easy it is to make even if the pattern does not already have one.
How To Make The Keyhole Neckline
Draw a straight line the length of the finished keyhole you want. The longer the line the more cleavage you will be showing.
Note: I am using a piece of an old drape, old stained bias to make this tutorial, so if you see the stains know that the fabric used started its travels somewhere in Asia 20 years ago, the bias tape is probably only 10 years old.
Mark the seam allowance above the end of the line. This will depend on the bias tape you will want to use. I like to use 3/8″ or 12 mm. I make a 4mm seam allowance which the width of the thinnest side of the bias tape.
Draw a keyhole from the seam allowance at the neckline up to the first dot which represents the seam allowance of the keyhole. Drawing the keyhole from the neckline will not increase the size of the neckline as shown in the picture below.
If you want to increase space at the neckline, start the keyhole from the edge of the pattern. The results are shown in the picture below.
Start the keyhole from the edge of the pattern with the amount of width you want at the neckline. See the drawing below.
How to sew the keyhole
Work on the right side or print side of the fabric. Cut the keyhole out.
Attach the thinnest side of the bias tape to the border of the keyhole.
Sew using a small stitch, I am using size 2 in my Bernina B 350.
Turn the bias tape to the wrong side of the fabric and use the stitch in the ditch technique or sew very close to the edge to secure the tape.
Finally, attach bias tape all around the neckline. Use this tutorial with my raglan sleeve t-shirt dress pattern in sizes S-2XL.
