Such a beautiful quilt and just gorgeous quilting. I rather like seeing the pineapple blocks on their own, allows you to appreciate the gradient of colors you used and your workmanship.
I've pieced similar bindings before, do you press your seams open or flat? I go open and sometimes when/if I piece a binding (or when I make my french binding), depending on the fabric I'll use a .5" seam, just like when you piece a back, but I typically use thicker bindings than most people and cut them starting at 3".
