Malaysian batik is batik textile art in Malaysia, especially on the east coast of Malaysia (Kelantan, Terengganu and Pahang). The most popular motifs are leaves and flowers. Malaysian batik depicting humans or animals are rare because Islam norms forbid animal images as decoration. However, the butterfly theme is a common exception. Malaysian batik is also famous for its geometrical designs, such as spirals. The method of Malaysian batik making is also quite different from those of Indonesian Javanese batik, the pattern is larger and simpler, it seldom or never uses canting to create intricate patterns and relies heavily on brush painting method to apply colours on fabrics. The colours also tend to be lighter and more vibrant than the deep coloured Javanese batik. In line with the Malaysia concept, the Malaysian government is now endorsing Malaysian batik as a national dress to every level of the general population, by having local designers create new batik designs which reflect the Malaysia idea. In Malaysia, batik is also considered a cultural icon, with "Malaysian Batik Day" (in Malay: Hari Batik Malaysia) celebrated every year on 3rd December. Many Malaysians continue to wear Malaysian batik every day for both casual and formal events. The origin of batik production in Malaysia it is known trade relations between the Melayu Kingdom in Jambi and Javanese coastal cities have thrived since the 13th century, the northern coastal batik producing areas of Java (Cirebon, Lasem, Tuban, and Madura) has influenced Jambi batik. This Jambi (Sumatran) batik, as well as Javanese batik, has influenced the batik craft in the Malay peninsula. According to the Museum of Cultural History of Oslo, it is known for certain that the Javanese influenced Malay batik-making technically as well as in the development of designs. At an early stage the Malaysians used wooden blocks in order to produce batik-like textiles. As late as the 1920s Javanese batik makers introduced the use of wax and copper blocks on Malaysia's east coast.
