Not a log cabin, those beautiful flowers would get lost. Love what MarjaMT did, those are gorgeous. Look thru some books/magazines and get some ideas, the fabrics are beautiful and you'll have a wonderful quilt from them. Orange is my favorite color and I love to see how others use it; I know a lot of people don't like it. I've never done a OBW or kaleidoscope but they'd be a great showcase.
Will look forward to hearing what you've decided.
