Miss Kitty,
Here are my 2 cents but you have a good start. I am doing a log cabin on foundation hand piecing. This technique it is already quilted when you are finished with no batting.
Log cabin is a great block with so many options. You can strip piece, paper or foundation piece, quilt as you go or whatever. Find out what works best for you. If you want to hand quilt it, I agree you should not use a foundation.
I am sure your blues are beautiful, but the bigger the contrast the larger the effect. If you want something subtle choose the contrasting side accordingly.
Look forward to seeing your top :thumbup:
