I agree with grammy Dwynn ... and add that the portion you have sewn remains on the surface longer. In my case I put a small Lifetime adjustable table behind my cabinet so the quilt top or whatever I am sewing never drags or drapes downward. If whatever I am sewing is really big, then I can also put another small Lifetime table to my rleft and it then carries the weight of whatever I am working on before I sew.
