To JanRN: I don't know if this will be helpful to you or not, but it might be food for thought. How my first 25 are laid out now (in order), they do not "work" at all. (I already knew they would not ... I did not make them to be in the same order that Laura has hers.) When I am finished all 111 blocks, I will arrange them to where they look best to me. Of the 64 blocks I've completed, I have some with not enough color contrast, others that will fit nowhere at all in the quilt and some that I dislike; any blocks that fall into those 3 categories will not be in the quilt. As a result, I will either have a smaller quilt or be re-doing some blocks. In the meantime, I'll just keep plodding along as best I can. It's been my experience that a little tweaking here & there can make a great-looking quilt.
If you need advice, certainly better to get it sooner than later, but I think you're doing fine.
