You could make a very ugly and useless sweater out of that yarn..

You need wool for nalbinding because it is worked with short lengths of yarn and you have to be able to splice it together. Tying doesn't really work because the knot has to go through the loops every time and it snags a lot. Acrylic won't stick to itself and splice together seamlessly like wool does. You could maybe use a wool blend, bit it would suck to put all tat time in only to have the item fall apart because the splice didn't stay together.
