Problem solved. Thanks to all for your input. I knew I could buy it at JoAnns and other online sources, but I would have to order and then have shipping charges. I had one wonderful quilter, "Nancy", PM me and she is sending me her ribbing stash. I think I will have what is necessary to fix most of the shirts for Jeff. If not, he gave me permission to turn them into V-necks and add a facing.
Thank you all again for your suggestions and help!
