I've been working on some new projects using a texturing compound that dries hard like wood, but can be applied with a piping bag and tip. Before doing an actual project, I experimented with the compound, and also with fabric paints, to see what the limitations were.
Here's a picture of some of the preliminary effects I played with, and some wood that's been prepped for an actual project. When I start off in this way, I never know where I'll end up, and I already have quite a punch list of things to try. Those that work will probably end up as published articles for everyone to enjoy, and those that don't are still a learning experience!
