If so, I agree that it will be a very looooooooog strip - that being said, a queen size quilt with a ten inch drop measures about 80 by 90 and translated into square inches that comes to 7200 square inches finished. If you translate the jelly roll strips into finished dimensions, I calculate each strip will finish out at 2 inches by 41 inches (of course the 41 could be 42 or 43, depending on the fabric width). Multiplying that finished dimension, 40 strips that finish to 2 X 41 comes out to 3,280 square inches. That means you'd need three jellyrolls to complete the queen, and you'd actually have enough there to make a quilt about 96 by 98...which is a queen with an 18 inch drip. you can also reduce the amount of the drop and make it longer to include a tuck over the pillows.
