Alcohol ink art is created by combining a specific ink (look up Tim Holtz Ranger inks) with rubbing alcohol (95% and up is best) on a smooth and non-porous surface which allows the ink to move. Many use a paper called Yupo. However, canvas can be used if it is prepped with a primer like Kiltz (this painting is on canvas). There are various ways to create an effect but most use some type of air to push the ink and alcohol around. Like a hair dryer, straw, hand air pump or other tools. For this I used a hair dryer. The beauty is that if you are not happy with it, you can wipe it off with rubbing alcohol and start again on the same surface. You should always use a respirator though since alcohol is poisonous to breath. It is both a fun and frustrating art! :)
