First of all welcome to the QB from SE Michigan! The purpose of quilting a project it to stabilize it all and all parts of the quilt. The embroidery you are suggesting is a great idea. You may still need to go outward from your focal point of the embroidery. If you are concerned about how even your stitching is this might help. There is a product called "Tiger Tape", when I first began hand quilting I used it to insure my stitches were even. the tape is marked is such a way that you will get a nice and even 12 stitches per inch or 15 stitches per inch, depending which one you buy. I still have a large roll of it here. I am now using it to teach my GD how to quilt even stitches. Here is a link for it:
