Very nice. :thumbup:
With regards to the borders being a bit wavy, try pressing them with steam and starch. They should behave better. I'm going to assume you had the border fabric on top, as you were sewing them on. The extra weight of the quilt top hanging down below your sewing machine created a stretching effect on the quilt top, while the border fabric was not stretched at the same rate. This will cause some slight waviness. Also, check that the edges of both fabrics remained even and the seam is a consistent width.
