The T-Shirt Quilt Book is a great book by Lindsay Conner and Carla Hegeman Crim. It covers all the basics about how to make great looking t-shirt quilts. It covers inferacing, piecing, and finishing, and gives some great design ideas that go above and beyond the standard squares. This would be a great book for a beginner or someone looking for different ideas about how to design a t-shirt quilt.
