When the three sections are sewn together, it should leave you with a 3 1/2" square cornerstone to be sewn onto the sashing at every intersection. Please notice that every intersection meets perfectly due to the use of the diagonal pinning as shown in #3.
Pinning the cornerstone sections together is very important. "But" the seam allowances together and insert a pin beside the seamline on both sides, but TURN THE PIN INTO A DIAGONAL position as shown in the illustration. For some strange reason, doing this makes the seams stay together perfectly! This is a great trick to learn when machine piecing at intersections. The seams will match up every time! AMAZING!
#2 step puts the light fabric on the outside edges of the strips. This will become the center section of the cornerstones.
