As a old woman who comes from a family of quilters my answers are my thoughts only and may not be what you are looking for, Traditional to me are the patterns my grandmother and mother used to hand piece in the 30's and 40's that were handed down from their mothers and grandmothers. In my mind the contemporary is the newer patterns that have come out in the 50's forward. The modern in my mind is the use of blocks, circles, cubes and shapes to create the pattern.Art quilts I love to make are cutting fabrics to make a picture or work of art from fabric. As for quilt shows I no nothing about putting one together I just enjoy seeing the beautiful work done by other quilters.
