Can you tell me which video you are watching? That way I can see exactly what you are trying to achieve.
To get more templates for your store:
1. Go to your store's control panel
2. Click on Store Design at the top of the page
3. Click on the Download Store Designs tab
4. Click on the link that says Click here to check for new store designs and follow the instructions
5. You can then see the design on the 'Store Design' page
