Fading
Do any of you do "fade" tests on your fabrics before using them in a project?
I think Harriet Hargrave had something about light fading in one of her books - but I don't have a direct reference to it.
I have a quilt made from blues and tans - some of the fabrics look almost as bright as when they were new- but one of the navy blues has faded so much that it is barely recognizable as having had a navy background.
Is there any way to predict which fabrics will fade out and which ones will stay bright?
(I'm not talking about bleeding or excess dye.)
