Tufts & grass, etc
I`m not very good at terrain and usually can`t be arsed to mess around basing figures beyond a basic flock style
But I do sometimes experiment and find 28mm stuff needs more effort than 20mm. Anyway, I ran out of tufts and our local model shop was closed for a holiday and I don`t do GW (fuck em)
So I went to Ebay and discovered this company - https://www.warpainter.net/
Bought this set of arid tufts for £4.90 inc postage - pretty good IMHO
