Well I've gone through a number of stages in the 20ish years I've been into painting miniatures. I started with the evil green dust, expanded into sand, worked up to gravel, then on to resin bases. But recently I've decided that no one option is really right. Each has its place, but no one is better than the other. On the other hand each has its drawbacks.
|You know the stuff... flocking material, in a basic green. Evil stuff... gets everywhere.|
|Typical 'gravel' flocking material. Not bad, but lets be honest it looks like big rocks with most 25-28mm figs.|
|A not too bad mixed sand/gravel flocking material. But even this has issues with the 'mini-boulders'.|
Overall I think this idea makes up for a number of shortfalls in most single or dual material flocking mixes. So I took my green evil dust, the sand/gravel mix, the gravel mix, some very fine sandbox sand, and a mix of sand/rock/gravel from the edge of a driveway (which oddly enough is a TROVE for basing). Gave it all a thorough shake and mix, and came up with this mix.
Overall this mix blends very nicely, and with static grass patches looks like your typical field in the late spring/early summer. With different mixes you could get any time of the year, or any type of terrain. So don't be shy on mixing those materials together to get a more natural look. It does look good and works much better than just one type of material.
