With large quilts the whole quilt gets rolled up into the throat of the machine. ( In the picture of mine the takeup bar is shown going threw the throat space.) On smaller machines the bulk of the rolled up quilt limits your movement. There may only be a few inches (forward to backward) that you can quilt. Side to side movement doesn't change much as you are on rails or tracks of some kind. It is posible to quilt larger (king/queen) size quilts on a smaller machine but it involves quilting half of the quilt then removing the quilt and turning/ reattaching the unquilted portion to the fame to quilt the other half. This is not a fun thing to do. There are probably other ways to do it that I don't know. Don't ever be hesitant to ask questions on this board, we all support and encourage each other and are glad to help clearify. I hope I explained this ok.
