I'm filling the body of the brooch with long and short split stitches, so that there's a shading from light in the center, to dark at the outer edge. It's a nice effect, and can really glow in the right light. First I establish the direction of stitching with long stitches. I'm not worried about the long carry of thread on the back, since that's all going to get anchored, with the future stitching. I'm also using two strands of floss, and the Milliner's needle, since that's going to be rugged enough to stitch through any glue that might have gotten into the middle section (there will be glue in the middle section, there always is) As a note, do remember to separate your strands of floss, it will give you better coverage, and look better.
The main section is done (before embellishing, there will be embellishments of course) Go have another cookie.
