Hi and welcome from a neighbor just up the road in Summerfield, NC. There are a number of books out that talk about using old shirts and ties but if you go to Bonnie K. Hunter's site, you will see that she uses shirts all the time for quilts. Check her out. She lives not far from us in the Winston-Salem area. She actually has a book out called "Scraps and Shirttails".
This is her blog:
