using a domestic machine like a long arm
Long ago I saw plans to build (or buy??) a little roller cart for a regular sewing machine, that you could move around on your frame table, so that it would function similarly to a long arm, in that the quilt is on the frame, and does not move, but the sewing machine moves up and down it. I cannot find my bookmark, and all Googling doesn't seem to find it either. Anyone know what this is called, or who makes/sells it? Thanks!
