Texture: impenetrable

I took a picture of a brick wall as bricks are solid objects that are hard to break

Texture: incised

 I took a picture of a table with some scratches on it

Texture: irregular

I took a picture of a wall outside in the courtyard at school as the surface of the wall changes constantly, and is not something that is typically seen in a wall

Texture: itchy

I took a picture of grass as when someone lies in the grass, it can be itchy

Texture: immaculate 

I took a picture of piece of shiny paper in an attempt to create an image that seems angelic, and thus be immaculate.
