Extra‑fine betweens with compact eyes designed for delicate, accurate quilting stitches. Size 12 suits fine cottons and tight curves where very small stitches are desired. The short length enhances rocking‑stitch control for neat seam lines and motifs. Ideal for experienced quilters refining precision on heirloom work. Follow package directions and test on a scrap for compatibility. Clean, dry surfaces improve adhesion and durability.
