welcome from OK. THough I will be in TX come THursday!
I am an avid quilt collector and am learning more about textile history from a very good source I found up here. A lady that worked as the state textile historian here in OK for the last 30 years! WOw...is she good...I find the old quilts and then together we document the fabrics.
another good resource is Barbara Brackman!
PM me if you have more questions about book on this subject.
