This is my method, which is similar to db's:
- Lay duvet cover out, insert hands to furthest corners, and pull the each corner inside out.
- Pick up duvet, and match two end corners to each of the pulled out corners as above.
- While continuing to maintain your hold on each corner bundle, lift the whole lot up to shake the duvet cover down over the duvet.
- Shake out in anger until duvet is evenly distributed within cover.
