nice quilt.
i am currently having the same quandry. i have started with some stitching around the blocks but feel it needs more on the large ones. in my case the pieces are several different sizes and i have added pieced blocks and photos to fill in between. so many different "things" to deal with. what seemed like a good idea when started has turned into a head scratcher.
good luck. i will follow along here to see what other pearls of wisdom come along.
