A quick addendum.

After today's update I started to work on the hex grid. Just the points touched in yellow on a Citadel battlemat. 5 rows in so far and looking good! I'm seeing spots before my eyes but is worth it. I'll finish it off tomorrow. What do you think chaps, size about right for my 60 x 60mm bases?  I plan to trim off the extra width and use it to cover my hill hexes so it all blends in nicely. I'll go back over the 'spots' and tidy them all up once the grid is completed.
