I have made a couple of GFG quilts. I cut my hexagons from freezer paper, and my fabric hexagons approx. 1/4" larger on all sides. Lay the freezer paper dull side down on the wrong side of the hexagon fabric and iron the 1/4" seam allowance to the shiny side of the freezer paper. They are so easy to hand sew together. The freezer paper hexagons can be used over and over.
