Made with acrylic yarn. Machine wash and dry on delicate. The picture with the hair tucked in is with long, thick blond wig. Will hold long hair and short dreads. Measures about 11 1/2" in diameter. I have seen other tams with motifs like this but this is designed by me with my standard dread tam incorporated with the motif. If you have tried one of my beret tams then you will know this is a great fit.
