I received a white comforter when I bought a new bed. White is not my color nor would it stay that way very long. The outer shell is 50% cotton and back 100% cotton. The idea is to dye it a medium to light color. From what I saw in your column it would be hard to achieve a dark color with the polyester content. What would be your recommendation?
my recommendation would be to make a duvet and put the comforter inside it. You can make one out of two flat sheets or a length of fabric. close up the end with buttons, hook and pile (Velcro), or ribbon ties.
