Okay, I have finished the last 1/4 of my bargello and have made a border decision. It was fun deciding what look I really wanted, and here is what I just decided. The borders aren't sewn on yet, so visualize each 1/2 inch skinnier when all is said and done.
Thanks for all your suggestions. This whole process has been fun, especially with all the help I got from lots of you quilters!!
