I have decided that pricing a quilt would be somewhat like pricing a diamond.
With diamonds, it's color, clarity, carat size, and cut.
With quilts, it's size, materials, difficulty, and workmanship.
So - when someone asks - what is a quilt worth? one needs to know more than just the size of it.
I suppose one can also add 'who made it' to the possible value of a quilt.
