I have added Army Painter winter tufts to my US heavy weapons teams, and I like how they turned out. I tried out the model railroad straw stuff about 20 years ago and only managed to get a lot of straw glued to my hands. For $6, I think I got a good value for 20+ tufts that only require me to use a set of tweezers and some glue.
While I was able to get the tufts through my local gaming store, you can take a loot at them on the Warlord Games' Army Painter Battlefield Basing page here. There are winter, swamp, jungle, and Highland tufts available.
I'll probably work in some swamp or Highland tufts in some of my other FOW models. Frankly, mixing tuft shades ought to be a good idea, just like mixing turf and flock shades - I see plenty of pastures and open fields that are not uniform in color or height, with patches of new, old, and dried grass/weeds all about.
I love history, mythology, and games. My favorite projects allow me to mix them liberally and turn readers onto something new and different. When it comes to games, players ought to do more than roll dice, flip a card, or move a piece – they ought to feel immersed. I look for this in my favorite pastimes and I bring this attitude to the table and my work. This blog features my thoughts and experiences about the games I play and my contributions to the hobby.
