Katybob, you crease & fold the first line(center side) take center & first row fabric, pin or press to hold in place then sew the fabric along the creased edge of the folded paper, flip fabric, trim, continue with the third piece of fabric & folding the paper back on to itself to sew along the edge.. pressing the paper to the fabric so they stick together..Do I have it right? do you cut your fabric so that you don't have to trim it?
