Most didgeridoos made today are for souvenir purposes. It is common to find didgeridoos made of non-native timbers, decorated incorrectly by non-indigenous artists with colourful designs or copied dot patterns. These decorations do not use traditional dreamtime stories or designs. These didgeridoos also often vary widely in size and shape, many being thinner and straighter. As a result of the inadequate wood types, shapes and lengths, souvenir didgeridoos can rarely be used as musical instruments.
