craftgrrl | Thick, heavy duty vinyl....what's it called? Where to find it?

Hello!

Can anyone here help me? I am looking to buy some of this type of vinyl...you know the kind....not thin tablecloth type vinyl, but the thick stuff that looks like leather? Like what they'd use for fake leather on cars and such? I have been googling it up and down, but there are so many types of vinyl...I am not finding any that looks like this...it comes in different colors...anyone know if it has a special name or where I could order some by the yard online? Thanks!
