For the traditionalists, you can combine Cornflake's and 'Spaw's methods with the standard technique, as follows:

1. Place a guitar on the kitchen table. (string side up)
2. While holding the dulcimer firmly on your lap,
3. sit on the guitar.

Note: Although you might be tempted to use an Ovation guitar for this, you do run the risk of a serious neck injury. Yours.

Aloha,
