I've always used templates to sew a 1/4" seam allowance around, after cutting out the fabric pieces. I can't imagine doing it neatly without the templates (maybe SimplySandy could make a demo video for us). I'm working on two hexagon quilts at the moment, one is 1" hexagons with plastic templates and the other is 2" hexagons with paper templates.
For the 1" quilt I used a clear acrylic template to fussy cut the fabric pieces. Then sewed a 1/4" seam allowance around plastic templates. Ironed the fabric plus plastic piece then pop out the plastic template to be reused. I then sew (whip stitch) the hexagons by hand into "7-mer" flowers, and then hand stitch those together to make the quilt.
The acrylic template I have is from the 85014 Hexagons pack.http://www.quiltsensebymarti.com/products.php
The plastic templates are these (which are available in my local Joann's).http://www.shopatron.com/products/productdetail/part_number=JUTJT-300/175.0.2000.27722.214.171.124#addp_Simple%20Shapes%20-%20Hexagon1
For the 2" hexagon quilt, I again used a clear acrylic template from the pack above to draw around and then cut out by hand with scissors. Then used paper templates, to form a 1/4" seam around. You can buy the templates pre-made ( for example http://www.cottonandchocolate.com/catalog.php?category=20
) but I just made cardboard template, then drew around it numerous times on an A4 sheet of paper, which I can photocopy at work. I cut out the paper templates while watching TV.
