I have one of those tables from Jo-Ann Fabrics too. I truly have used me extensively and yes, you can use half of it at a time. You see, the supports for each half of the table swing out from below the center of the table and can be positioned anywhere under that side of the table and the other side works identically. However, that said, if the swing support underneath the table half is not positioned right, it will not provide enough stable support for that half of the table. Nothing wrong with that, but you need to know that before using the table.
