how to drop quantity choice in shop

[Claus Vesterager Martinus]

Hi
I'm doing an artshop for a client. Her paintings are unique so when sold, that's it. So I really don't need the quantity choice in the product page as there's only one item to be sold of each painting. How do I drop this option?

Yours

Hide with css. 

Something like:
.quantity-input { display:none; }
.quantity-controls { display:none; }

Create an override of addtocartbar.php sublayout.
