Silk, I like your block! You have a good sense of light, medium and dark balance in your colors.
I am thinking of twin quilts...like, well, two of them 'cause we have two children claiming and proud of their parents. One will need to be a king and one a queen... if I can have the energy to do the work and the sight to measure right. So I will try one first, and see what happens about the second one. I keep visualizing a blank block, actual size and putting the fabric pieces where they go on the block and not quite seeing it. Maybe if I drew it out on drafting paper.
