no its made with acrylic yarn.
i'm not a fan of making sweaters, ive only made one my whole life and it was very ill fitting even though it was suppose to be baggie. sweaters take a lot of time so it would be very very very pricey.
if you really wanted one what i would do would be buy a black long sleeved t-shirt and white fabric paint (they come in pens which would be nice to use)and use a fabric crayon to make the pattern on the shirt then trace it with the paint on your shirt.
this will take a day maybe two, and to make a sweater would take me a month or two
