I have always placed them horizontally but at the top of the placesetting, they are too long to place vertically and they look funny! Rice bowl on the left and soup bowl on the right is similar to our "proper" table, solid foods are placed on the left and liquids are placed on the right. As another lefty, I've never had any trouble using chopsticks, the best way is to pick them up and use them, no photos or instructions! That can be confusing for a lefty! Changing light bulbs is still a bit of a challenge, can't tell you the number of bulbs I have broken off in the lamp....
