The completed hex tiles.
I recently needed a few single 'desert' hexes to add to my existing Hexon collection. As I had 'flocked' my own desert set (the original pre-flocked desert Hexon was a bit too orange to my eyes...) I used a few of the blank (bare brown plastic) hexes I bought at a show earlier this year. It occured to me while engaged in this process that it might make a useful post for others considering a similar course of action.
First I washed the plain hexes in soapy water and rinsed them thoroughly before leaving them to dry overnight. Next I 'painted' one hex at a time with a liberal coating of PVA and doused them with fine sand - as per the photo below.
When dry, I dabbed on further blobs of PVA and piled on clumps of 'grass' flock. This is a good way of covering up any 'bald' patches in the sand. Finally the tiles were treated to a blast of spray varnish.
