I had a quilt pieced by someone else. I was trying to quilt it using the "Stitch in the Ditch" quilting pattern. I could easily identify the seams that ran vertically down the quilt.
I was having a difficult time identifying the seams that ran clear across the quilt horizonally.
My mentor said to start in one corner with my 9 1/2 inch square and measure a square of 2 inches. See if that horizontal seam would go clear across if not try at 3, then 4 and so on until I found the seam that ran clear across the quilt. I finally found it at 12 inches. Does that clarify?
But this thread is about sharing that piece of quilting advice that helps you the most when quilting.
