The bobbin ring from Prym ensures safe and orderly storage of the sewing machine bobbins. The plum blue ring made of soft plastic can hold up to twenty bobbins and also prevents the yarn from unwinding. It can be modeled into the desired shape using a simple trick so that coils of all sizes can find a firm hold in it. You put it in boiling water for 15 to 20 seconds and shape the two edges to match the diameter of the coils. A short bath in cold water gives it back its original hardness and remains in the modeled shape.
