And so you believe it is morally permissable to wear those formerly banned “blends”?
A blend is a blend of different fabrics. For example, wool socks and a linen shirt is not a fabric blend, but socks made out of a blend, an interweaving of wool and linen fabric, are. There's not enough information to judge whether it's a moral or practical issue. I would say that if God said not to do it then there's a good reason not to do it. That reason may not be evident, but it's still there.
