Once again, I have changed my mind and am including a fourth fat quarter to the tones trio - it finishes the set, but of course no longer a trio but a quartet instead! These will be listed on my etsy site: Ten Pines Studio. Like the previous set of fat quarter they are made of raw silk known as silk noil and are hand dyed by me. They are a semi solid mottled set. I am very pleased with the result.
