I like the way your border looks. The black sort of frames the quilt and the zig zag adds interest to the quilt. Neat pattern and great job for a first quilt.
As for hand quilting. I did the same for my first quilts.
Question what will the quilt be used for? If you save your hand quilting for "forever" quilts and tie or machine quilt the ones that are more utility quilts.
I have enjoyed both worlds hand and machine.
Enjoy!
