Thank you for all the great advice (and the welcome): I will make sure the quilt is protected from moisture, put it in a plastic bag and maybe a box too and will pay extra to have a signature for it. The value is a bit dicey as we all know that the cost of quilting flannel is significant and it is a queen sized quilt. I will not include any estimate the value of my time or work.
Good point on labelling it "bedding." I don't want it to disappear en route. I'll hold my breath till it gets there safely. Thank you again!
