Some fabric that I use in a quilt I prewash, some I don't (for small pieces like 1/2st's). When I am all done - binding - all done - I take it to the laundromat and put it in one of those big washers on gentle cycle and sit there and watch it closely. I don't want anyone stealing it!!!!!! Then I put it in a dryer on warm and get it just about dry, take it home and hang it on the line until it is all nice and warm from the sun and smells like Spring.
Then I give it away! Edie
