I can't handle the floor, either. I don't make really large quilts so this works for me. I lay as much of the quilt as will fit on the table and tape it down. What doesn't fit gets taped to the underside of the table. I pin what is on the table and then I remove the tape, move the quilt over for the remainder and tape again. It seems to work pretty well. Might be a problem for a king or queen but I think it would work for pretty much anything else.
I can't take the floor, either, and, thus, it's hard to get myself to finish the quilt.
Thanks for helping me do this better on a table too small for the quilt top.
