These little clips hold seams closed, both during seaming and while awaiting seaming, to keep the knitting from stretching out. This is especially helpful for collars and underarms in top-down, seamless sweater knitting. If you knit in pieces, these are the perfect clips to use while seaming to keep your seam on-track and perfectly matched. The matte white/translucent color is subtle against any colors – so the focus is on your beautiful yarn, not the clips.
