Check their fabric selection in the drapery department. They have a line of solid colors that may be ok for quilting.
I bought a piece of fabric with white back ground with angles in silver/grey - like the weathervane which is quilting weight. I will quilt it all over and not cut it up. Their fabric is 60" wide and it was $2.99 per yd. Our local no longer carries the lighter weight fabric - more drapery weight but you might be lucky. I also bought a 4 pack of thread for $2.99 that is primary colors and good thread.
