In a previous posting I wrote about using "splinters" to represent the kind of deadfall you find in the woods and bogs. I spent more energy that I care to admit settling on a source for the splinters: block planer shavings, chainsaw chunks, drill bit waste, ... In the end I used the dried up branches one drives over time and again on the driveway. A hand full of this material will spread out to a square foot of forest floor. Just split off a chunk, flatten it a few times with a hammer, and then pull it apart.
