Welcome from AZ. As you will soon see for every question, you will find 100 answers LOL. And as with most issues, do what works for you. While attending classes, I've seen a lot, if not all, variations of transport. From fancy $3 or 400 cases to milk crates zip tied to folding hand carts. If you are rolling your machine hundreds of yards to get to where you are going (plane), use a well padded container, if you are parked in front of the shop, usually no cart is needed, depending on your physical condition. You will see the statement "your quilt, your rules" multiple times on the Board. It applies to most questions, just use the answers as a general guideline.
