Not usually with a kit, because they build quickly, but I have 2 projects that I have been working on for the last few years. I do others along with them, but when I get in a pinch, get stymied for ideas, or just plain don't want to mess with it anymore, I put it away and come back to it later. Put it somewhere safe and if the urge comes back to play with it you can. Santa brought me the Don Smith 169 inch B-29 plans so that will be the next multi-year project!
