Purl Strings by Minnie and Purl
The sweater plus pack of try-on tubing includes 3 silicone cords… one piece is 2.5 meters long for the sweater body, and two pieces are 1 meter long for arms, or child’s sweaters
To use, simply insert the tip of your needle inside the opening of the cord end on both sides, move your work to the cord, and now you can check for fit as your project progresses
Comes in a metal tin
