After attending a quilt showing of Gee's Bend quilts I witnessed exactly the type of quilting you have described. They worked with materials available, either donated or old used clothing in various degrees of wear and fade . The quilts are now being shown as art in museums. It is my thinking that as hand work is becoming less popular any of it is to be honored and cherished for who knows what 20 more years in the industry will bring. Another example of original quilting was an antique schoolhouse quilt I bought and sold (when I was an antique dealer) where there were houses on one row and not another, some upside down and some right side up. This quilt was featured in a quilt book as an inspiration for quilters. There were blocks of various other sizes and patterns in the same quilt. The backing was many different colors and patterns of ticking which had been laundered many times. Do what is comfortable for you and please let us see your results.
