LINES- lines can be very different. But look the same. There are many reason why lines are different. The size, the length, the shape, the colour, there are so many reasons. Lines are everywhere. In your home, in your town, in the forest. Everywhere.
TEXTURE- the texture is how things feel. lots of things feel different. everything has a texture
whether its smooth, rough or bumpy. There are many textures. 

SHAPE- Everything is a shape. Without shapes the world would be straight. Shapes are things that bend, turn and flow.without shaes the world would also be very boring.
