Here’s a photo tutorial on modeling tall grasses, using old brushes.
It looks like you’d be able to get quite a bit of material out of one of those cheap house painting brushes.

Modeling Troy For Skirmish Gaming
While not quite a tutorial, 15mm Wargaming for Fun and Sanity has a great article on modeling a mud brick / adobe town. The build was designed for ancient Troy, but as the author notes, such buildings are extremely versatile, applicable to more periods than you can count — even science fiction.
I’m inspired.
Making A Pill Box
Wargaming Miscellany has a photo tutorial on making a bunker out of a hexagonal craft store box.
It is amazing what you can do with just a little imagination and things not intended for the task.
Making A Raft
Wee Blokes has some instructions on making a raft for your miniature wargames.
The core materials are sticks picked up on a walk in the woods.
Adapting Individual Basing to DBA Style Elements
The 15mm Wargaming blog has a nice little article on how he adapts individually based figures to DBA style element basing.
I find it interesting because I do a similar thing myself. All of my ancient and medieval figures are individually based so that I can use them in various skirmish games. However, I also have some magnetic “movement trays” that I stick them on for element-based games (mostly Might of Arms). My cardboard and magnetic vinyl bases, however, don’t look nearly as good as the ones in this article. I base mine on 1 inch washers, though, so I will have to investigate to see what similar things are out there for that size.
