I went to a quilt retreat that had a lot of classes and one was on how to block your finished quilt. It involved spreading out the quilt on towels on the floor, measuring all the edges to edges, then dampening the quilt to block it. Then repeat if applicable. The teacher said all professionals do this, now I'm surely not a professional, but I have not ever blocked a finished quilt....this is after binding is on too! Does anybody on this board block their finished quilts? And, is it a long tedious process.
