Terrific advice, I am learning from everyone's posts.
I appreciate your detailed thought process, petthefabric, and will use your advice. I appreciate specific examples on real life blocks.
QuiltedSunshine, I envy your experience working in a quilt shop. What a great way to learn color theory hands on. If I ever worked in a quilt shop (in another world and dimension) I fear I would go broke, LOL.
And I def plan to use my camera to take black & white photos of proposed blocks next time. It's all a great learning process!
