I just learned a lesson on washing.. I missed washing a fabric in ddil's king size quilt she was just given. My son put it in the dryer to freshen and get folds out of it, applied a little steam to help and one color ran all over white dashing around that block. Thank goodness I used it for just one block so the whole quilt was not ruined, happened to be on the bed over hang. But backing was ruined.
