Business and Hobbies Issues

I just go the pack and have been having so much fun with my small pottery business. However, My sims keep making items and leaving them everywhere making it so other sims cant use the wheel or kiln. I also cant pick up the items sims leave to resell. Which is annoying because if they don't take it with them I want to resell it. Is there a way to help sims leave with the pottery they have made or a way to resell it myself by putting it in my own inventory?
