An American standard of yarns !  This is the yarn that my grandmother first taught me to crochet with when I was four years old.  It still holds a dear place in my heart.  Great colors and holds up wonderfully even after years and years of washing and drying.  I have an afghan I made when I was eight years old.  It is a little bit wonky, since I was only eight years old.  The whole afghan isn't Red Heart but the larger majority of it is, and you can tell which yarn is the Red Heart yarn.  It has held up after all these years.
