I am doing a GFG as we speak, also. I use the magazine inserts that are always falling out as you open one. Good recycling...and good weigh. I cut trace the hexagons on this paper, put them on fabric and cut 1/4 inch larger around the hexagon. Then fold over the 1/4 in and it shapes around it perfectly. The corners are so crisp and smooth. I baste around the hexagons then sew them together...and will eventually press them and take the basting stitches and paper out.....English paper piecing.
