Great runner!! I'm sure your niece will be thrilled.
.. and thanks for the inspiration, as I just happen to have some similar border print fabrics that I never know what to do with. Now I have no excuse!!
You sound like me .... have an idea and make it as I go, but then I have another idea and oops, kind of messes with the first plan's execution. Ugh!
But that's how we all get originals instead of cookie cutter quilts that EVERYONE can have!
