After 30 years of quilting I have narrowed my preferences to 2 companies and 2 fibers.
Wool because of its light weight, easy of needling, warmth, washability. My favorite bed quilt is wool batted. I've used both Hobbs and Quilters Dream.
Cotton Select from Quilters Dream and Hobbs Organic Cotton because they wash well, wrinkle just enough to create the vintage look I prefer, needle well for handquilting, and can be quilted just far enough apart for my taste. Quilts made with these fold and store beautifully for me.
