A friend of mine appropriated a piece of an orange construction fence that is an especially good find. It's really flat, with no bumps, and that not only makes it good for printing the fence, but also thru it.
The picture above is the new fence drying on a bench in my yard, after I gave it a good scrubbing. It was really muddy. Now it's clean enough to bring inside and use for printing (soon).
Thank you to the person who gave this to me! I really appreciate it.
