black batting, black backing. and quilt close enough to add strength to fabric. we stay in a learning curve while quilting. i have done similar things and have finally learned the most important thing about fabric is not price....it is quality, quality, quality. so, hon, don't be so hard on yourself. learn from this. the quilt is beautiful. finish it. just don't invest any more time on thin fabrics. now, roll your shirt sleeves up and go to the next project.
