Change Size of desktop icons

Hi guys;

Continuing my Ubuntu learning experience, I have managed to do this before but cannot recall how, My Icons on my desktop have changed and are now tiny, I also notice i no longer have the option to stretch the icon? when I right click..


How can i change the default size of my desktop icons?

Any help appreciated..

Thanks........

UPDATE:

Ok I found "Stretch Icons" but dont want to have to do this for every icon i put on the desktop..

Thanks,

Cheers for the speedy reply..
Works a treat!
