Ta da! You’ve reached the namesake for this site. Anytime you run across some little dots in a pattern this is the stitch to use. However, it does make a knot on top of the fabric and sometimes you may want something more subtle. I use a teeny tiny cross stitch to accomplish this.
Cross stitches are very useful as fillers or edgings or just about anywhere! A long time ago and in a land far away a little girl’s gingham dress might be embellished with rows of cross stitch embroidered in a contrasting color.
