These little clips to 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.
