Maya - Texturing

Ive learned how to add textures onto the object!! (Still learning though...)

Ive found these textures from google and applied onto the object. I think it gives more definition to the object rather than sticking with simple textures (such as plain colour Lambert, Blinn etc). 

The texture sort of stretches when I stretch the polygon or extrude the surface but sometimes these 'stretches' gives good textures (?) The Image on here is showing the texture of the mattress.
