Vintage pieces

I have recently acquired these three pieces of vintage quilts or quilted fabric. I have been reading Mandy Patullos book and she uses old parts of quilts as backgrounds for more appliqué and embroidery. So I am inspired to work these into something more to just go and see where it takes me. So the first pink piece is very sweetly pink, crisp and clean , has thin soft wadding and a pure white muslin back. I imagine this fabric could be bought off the roll . It has machine quilting in the typical bedspread of the  age manner. I am going to dye it to give it an aged look , not sure if it will be tea dyed, or onion skin or if I go to rust or botanical dye with eucalyptus.
