I have done the lines one way and will now do another lot, making nice squares. I'm not doing them "in the ditch" but about a half inch from the seams. I will bind it with the same fabric as the backing:
The back is looking good also, though it may be a little difficult to see. For those who were interested, the bamboo batting is wonderful to work with. It is so soft, and the needle easily pierces it. I think it is a lot nicer to work with than the cotton batting I usually use. If it wasn't so expensive, I would love to be able to use it all the time!! I do thoroughly recommend it to anyone who is making a "special" quilt.
