I also made the mistake of buying the Flynn frame and it now sits in the closet.
It is fine for baby quilts but they are not that hard to quilt without a frame.
You would need as much room as a long arm quilting frame uses since the frame needs to go from side to side all the way across the quilt. And handling it is very difficult at that size. Yes the rollers keep falling off the table.
I think you are supposed to use plastic pipes to extend it.
