I bought pre-cut hexagons from Keepsake Quilting. They are very nice and saved me a ton of work I didn't want to do
I was watching a lady sew itty, bitty hexagons (english paper pieced) and she simply cut squares and loped off the corners "good enough" since she was basting around paper anyway. Seemed smart rather than deal with the angst of exactly cut hexagons.
