I have a BlockRockIt and it is not a sit down machine. I use mine on a Little Gracie II frame. It loads just like the big boys and I move the machine not the fabric. They have released a sit down machine recently but it is new. The support from Lynn and Kathy is great as is the Grace Company who makes the machine for them.
