I am using tartan flannel to back a T shirt quilt. (I always wash all my fabric, so it was no trouble for me to wash it.) Just for fun I measured the tartan pattern before washing (it is a totally symmetrical pattern - there's a name for that but I don't remember it) and after washing...and the flannel shrank (shrunk?) measureably differently length of fabric vs width of fabric, so that the pattern repeats are no longer the same. That could have significant repercussions for piecing, if your cut pieces shrank (shrunk?) differently in their two dimensions.
