I use Kaye Woods' method for rotary cutting hexagons with a 60 degree triangle.

Cut the freezer paper whatever you want your finished size to be and cut the fabric 1/2 inch more (1/4 inch on the ruler). I don't thread baste the fabric onto the hexes, though. I just fold it over and pin. I take the pins and the paper out after a portion is surrounded & yes I do get stuck by the pins but I hate basting.
