Even if youhave lost all your paper work you can write out the info required and they'll be able to process the return, though it may take afew days longer because there won't be barcodes to scan so will be entered manually. You'll need you QVC membership number, the order number, item number (and if you bought more than one ofthe same item (eg clothes for size) then add which size or colour you are returning, name, address etc. just written on a piece of paper will do.
QVC will just advise you to write the return address on the box, they're reluctant to send out a paid return label unless the item is faulty.
There used to be a link on the Q website all about returns.
