I would not make the table any larger in depth than a large cutting mat. I have a queen size bed & even though I can walk around it, I don't think I could do much in the center as it is not readily reachable. For sandwiching queen size, you can use the binder clips to secure the quilt to the table & do the pinning/basting in sections. I think storage is a bigger issue than a very large table. My sewing table/cabinet has a hindged drop down leaf on the back side that does not have to be up & taking up space all the time.
