  • Patent number: 9719200
    Abstract: An apparatus and method for suspending a substantial portion of a quilt or fabric for free-motion stitching during sewing operations is disclosed. The apparatus includes a planar frame with support poles extending from the frame feet, with a retainer for retaining a portion of the quilt or fabric attached to one or more support poles via a retainer block. The frame includes at least two frame base portions with frame feet on opposing sides of the frame base portions which form a secure base for the suspension assembly to rest upon a surface. A dowel spans between the frame feet of each frame base and serves to provide a sturdy structural connection to which the support poles are attached. The retention clips retain the quilt or fabric layers in the desired suspended position so as to form a partial paraboloid shape with the local area around the vertex of the partial paraboloid shape positioned in relative juxtaposition to the sewing machine needle where stitching occurs.
