Retreat Report #2

The first project I planned to work on at retreat was my mystery quilt from Quiltville. When I arrived at the retreat I discovered that 3 other quilters were sewing the same mystery...small world! One quilter was assembling her blocks, and the other 2 were working on their piles of 9 patch blocks. It was fun to see their quilts developing and I hope it was encouraging for them to see my finished top.
I had already finished piecing the quilt top before the retreat and my goal was to cut and sew on the borders. I had a black and white fabric from my stash that I thought would make a fun inner border and I cut and pieced it so the sayings would be complete around the quilt...that took some figuring.
Then I cut the fabric for my outside border, which was my only stash fabric that was suitable colours and a large enough piece. But I came up a little short, so had to add in corner stones. Here is a close up of the corner borders. I might take those blue corners out and make them green if I can find enough pieces leftover. I really cleared out my greens and the black and whites from this mystery quilt! What do you think...should the blue corners stay or go?!?!
