I look at it this way. Many people are collectors - stamps, commemorative plates, old fashioned toys, etc, even tractors. Most stuff that is collectable is in no way useful except that it gives the owner pleasure, and if it doesn't interfere with living a normal life, I say go for it. At least our fabric collections will ultimately be useful should we choose to sew with them instead of just admiring and fondling them. Now, excuse me while I go adjust a pile or two.
