I used this as a child and cannot remember what it is called or how to use it! It is plastic and about 2 inches long and 5/8th inch diameter with four small posts. It makes a long "tube", using yarn or string and wrapping yarn or string around the four posts, with the result coming out the bottom looking like a "braided" tube. It can be any length. Any help in identifying it and using it would be greatly appreciated! Thank you!
