The first Pintangle TAST stitch is Running Stitch. Seems simple enough, I looked into some inspiration from Sashiko stitching to learn something new. One skill (or practice in my case!) is to get all the stitches the same length and cross without overlap.

Running stitch done in variated green DMC Cotton Perle 5, lazy daisies sewn with red DMC Cotton Perle 10.
