I'd like to make a quilt with a design such as the one in the picture:
I understand that normally, when a quilt is just made up of squares or rectangles, you can just stitch a bunch of lines up and down and across it to attach the backing and it will still look good because the geometry doesn't get broken.
However, I'm not so sure that it will work with a design like this. The stray vertical and horizontal lines would look awkward here (I feel like) ... I know that another way is to just stitch again along where all the pieces connect. My question here would be as follows. If the backing is black, would it be better to use black thread to go over along the edges of all the pieces when connecting the backing? This way there wouldn't be an awkward design on the back of the quilt, but there would be ugly black thread on the front. Or, should i use the same color thread as on one of the neighboring pieces? This way the front would still look ok, but the back would have a strange colorful design...
Are there any other (better) ways to do this? Is it possible to not attach the backing at all, other than around the perimeter or would that not work so well?
