Hollow silicone tubes to use as stitch holders.
Simply press the end of the tube on to the tip of the needle and gently slip the stitches to the cable for hold, and vice versa for placing the stitches back on to the needles.
These can be used for putting sleeves on hold or for the body when trying on a garment, or when you need a needle for another project (like right now).
Sold as a set of three cables (1 x 2 yards (72 inches), 2 x 1 yard (36 inches) in a metal container.
