Add Dimension to your Quilt with Gathering: Crossing a SeamJanuary 8, 2010
I learned a neat trick lately to use when gathering fabric across a seam. When gathering stitches have to cross a seam that joins two pieces of fabric, that extra layer of seam allowance fabric thickens the gathering and it will not lay as smoothly as the rest of the gathering.
Here is a simple way of avoiding this problem. Stitch the two pieces of fabric together and press the seam allowance open.
Mark the points where the gathering stitches will cross the seam. I like to use the purple disappearing markers.
Then notch the seam allowances and remove the fabric at those points. Take the notch as close to the seam as possible without compromising the seam.
Stitch the gathering stitches through those notches and gather as needed.
This will free up the seam allowance from the gathering and the gathering will lay smoother.
And it will work whether you are hand gathering, machine gathering with a basting stitch or machine gathering using a ruffler.
