Squarehex launched a Kickstarter campaign in order to get funding for a Numbered Hex Pad. They’ve already made more than 2x funded (granted, they weren’t looking for a lot), so it’s stretch goals for the next 27 days.
From the campaign:
The purpose of this project is to fund a print run of A4 sized, numbered hex paper pads. The sheets will be litho printed with light grey (cool grey 5) 14mm tall hexes in a landscape format (giving 23 x 14 hexes per sheet). The pads will each have 25 sheets glued along one edge and be attached to a backing card.
