Your Lone Star Quilt is fantastic, you did a nice job coordinating your "scrap" fabrics to make a beautiful quilt. I do like the dark grey background, gives the star some bling. I have had no experience on an antique sewing machine, however, it seems to be in excellent shape. I might go with a blue or green for the binding, just my opinion, just pick a color out of the star and it will look great.
