Hobbs wool
Fairfield - bamboo/organic cotton 50/50- I preshrink this and it still shrinks a little more when washed. Available at Joanns and Hancock. It's a little more expensive so I stock up when it's 50% off.
Quilters Dream Poly- the charcoal color for dark quilts I don't want to risk any bearding on.
Hobbs 80/20 has changed. I don't use it as much anymore.
