I just wanted to share this 'find' although it's probably of more use to UK gamers.
Getting hold of a decent hex mat to start air wargaming has been a bit problematic due to shipping costs, waiting times, high cost etc.
I was initially looking for a sea mat. Rather than get a blue cloth I decided to try my luck by looking at blue vinyl flooring at a Carpetrite (a national chain for non-UK members). What I did find was a mottled blue hex pattern called Cortille 574. The hexes are 30mm across the flat. A section measuring 2m x 2m cost me £29.97 GBP. The vinyl itself is fairly thin at around 1.5mm so its easy to roll up and light.
The Carpetrite website doesn't feature this, but I did find a picture at best4flooring.co.uk (link below).

The actual colour of the mat is a bit brighter than shown in
the above link.
There is also a plain matt black 'mat' with a silver hex overlay. If I knew of any decent nightfighter rules I may have been tempted to get that as well. It may be of interest to the Space gamers here.
