Grafitti Knitting (aka urban knitting) is the illegal activity of applying knitwork to foreign property or state property. This kind of criminal behaviour is mostly observed in urban areas.

Traditional “grafitti artists” have been prosecuted due to the damage their work inflicts on foreign property for a long time, but since knitted grafitti can be removed at almost no cost, prosecution of knitting gangsters on the basis of the malicious injury of property is practically impossible.

Nevertheless the public display of unwarranted knitwork may still be considered an act of public indecency or terrorism and poses a general threat to homeland security.

Since knitting grafitti is an addictive and expensive activity it may give rise to economic-related crimes. Young knitting-addicts don't have enough pocket money to afford large amounts of wool, so they are likely to start pickpocketing in their local wool shop, or trade drugs to finance their expensive hobby.
