we get questions like this very often. unfortunately ... we end up with page after page of argument because everybody has an opinion that they are convinced is based on fact. :lol:
it is true that different fabrics will perform differently over time. some will fade, some will wear out, some will not. many will swear on a stack that it has everything to do with where you buy it. i'm not convinced that's a reliable determinant.
whether or not a quilt fades is primarily determined by how it is displayed, stored, laundered and/or otherwise cared for.
