I have 4 of these extension tables for my machines and would not be without one for quilting. i especially like them when doing free motion quilting and putting an easy slide sheet on it. It is also helpful to keep the weight of the quilt from pulling on the needle as you sew. They do seem pricey but they are worth it. I have the large ones and the small ones and it depends on what I am doing as to which one I use. I use the lage ones mostly when I am making large quilts and the small ones for FMQ or wallhangings.
