Sheree your blocks are stunning! I love the three colours.
I played around with doing three colours too, and there are some blocks that just can't have all three. After I'd recoloured the whole quilt I sat back and looked for any that jumped out and rearranged the colours. You can see at a glance if there's too much red, or too much blue in one section of the quilt. As long as you balance those out it will look fantastic. I can't wait to see more, they look really good!
