So to help with my hexipuff production, I made a hexagon template in Word so that I can block all my puffs to the same size. I think if I block them larger I won't have to make as many - in theory anyway. My template has worked out to be 4 cm in length per side. I printed a page of 6 on manila cardstock and if I print 4 copies, I can fit 24 on one blocking board.
I was going to just keep moving my template over after pinning the 6, but found my pins blocked the paper, so the puffs will just have to dry with the templates in place.
There's my template, simple as it is :)
