They now have some rubber backed, textured sheets 12 x 9". A wide range of colours from dark and light brown and green, blue and a lovely desert colour. They are heavy enough to lay flat and not slip and take ink readily to put the dots on needed form some rules. AT £1.5 per sheet they are a bargain.
I have attached a piccy of my WOTR army for BB by Peter Pig to show the sheets.
