I used a very small size 9 needle, with dark invisible thread in the top and black Masterpiece in the bobbin. I experimented with different stitches on my machine, and chose one that is a blanket stitch with a very narrow width.
That lavender pointed petal on the flower is bothering me. I left an opening so I can add a little something to it. Perhaps some hand-painted lace, gathered to make a ruffle?
