Purl Strings by Minnie & Purl

Purl Strings let you try on your handknit sweaters during different phases of your project so you can get the perfect fit.

The “Sweater Plus” pack of try on tubing includes 3 silicone cords. 1pc is 2.5m long for the sweater body, and 2 pcs are 1.0m long for arms or child sweaters.
To use, simply insert the tip of your needle into the opening inside 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.

Tube works best up to a US 9 needle size.
