I'm liking Stay-Flex, a woven fusible that is often used in tailored clothing like suites, etc, for stabilizing now after having used Pellon 911F, Pellon 906, and Flex-Fuse (a fusible knit stablizer that does stretch in one direction). It comes in both 20" and 54" widths. One of the problems with using the Pellon is the width is 20" and on a full size quilt that may be hard to keep it all together while quilting.
