I cut my hexes from freezer paper, and the fabric hexagon 1/4 inch (approximately) larger than the paper. Lay the freezer paper dull side down on the WRONG side of the fabric hexagon and press the seam allowances on all sides. The seam allowances will stick to the freezer paper It seems even to help when hand stitching the hexes together to have that freezer paper in there to guide the needle very close to the edge. The papers can be used many times again, so you don't have to cut enough for the entire quilt. This is so much faster than basting around each one, then having to remove the basting.
