I love the materials but... you asked for opinions. The blues are nearly all the same tone/shade. Need some darker and some lighter to give depth or dimension or contrast depending on your pattern. Another color usually works in a pattern to add a note of surprise but not this green. Another darker green or go with contrast and use a golden yellow which will look beautiful against this blue. Have fun playing with other fabric colors.
Please let us know what you decide on and we would love to see the quilt when finished. Happy quilting.
