I am in the process of getting a new/bigger quilting room and my DH and I will make making this table for cutting.

It does not adjust, but if I need one that does (I haven't yet in all the years I have been quilting) I will use a 30 x 60 table that my DH purchased at Lowes, to which I will add the extenders that one puts on the bed legs to raise it up.
I also have the Horn 5180 and the Horn 3140, which I have placed back to back. This gives me lots of room if I am working on a large quilt.
