I guess I’m a contrarian at heart - I love doing swirly quilting on geometric patterns and vice versa - sometimes the juxtaposition brings out the best in both styles. And I love echo quilting partly because it’s so relaxing - not too much thinking required, and as you go on, and if you are as undisciplined as me, it can take on an evolution of its own that can produce wonderful results. As someone else has already said, though, your quilt is beautiful and anything you choose is sure to work.
