I would frame it first with a small one inch cut border...black...is always good..give the eye someplace to rest since the eye has so much to look at...dark brown would be good too! Then I would use one of your colors that you used in quilt. Nothing pale because it will look washed out. I like the gold used on right side house roof..something bright and cheery. A pale yellow or white would wash it out. if you have enough left over fabrics you could make a piano key border as well. If not, I definitely like the idea someone else said of a scrappy binding! Just put the pattern in my Craftsy cart...thanks for sharing!
