I am impressed with your art making. While I have a million ideas in my head and materials to create multiple works, I have only done one. My cradle boards are 2” deep and probably not as cheap as yours, but I still find them affordable. I think the biggest hurdle I am facing is fear of failure and creating visual garbage. It one thing to do that with camera where the offending imagery may only live on a computer and never make it to the world of 3 dimensions, but quite another to make something that may potentially one day find its way to a landfill.
