Thanks Tlrnhi---I'll have to try it, too one of these days.
Renee, flannel shrinks but not as much as "flannellette". They look pretty much alike, with flannellette being slightly less luxurious until you wash them. Flannel won't pill or shrink half as much as the other. You'll find that the flannellette doesn't keep the square shape you had it in after the prewash, but begins to take on a slanted square almost diamond shape. HOpe this helps. Best of luck to you.
