When I moved and most of what I moved was craft stuff. I made a goal for myself right there. No more buying until I had finished all the projects I already had except what I needed to finish a given project. It took 5 or 6 years but I finished off everything and now I get what I need for a project and complete that project before I buy anything else. I'm sure if I weren't on a fixed income I'd be doing it different. But this is what I do now. So for me it's hoarding if it doesn't belong to the project I'm working on.
