Trinity, Cluster, or Bramble
From the Barbara Walker Stitch Description: This famous pattern is also (erroneously) called Bobble Pattern, and it probably has a few other names as well. It is one of the best of the “knobbly” texture patterns and is often used in panels to help embellish fancy-knit garments like fisherman sweaters.
