Hieroglyphics can be read from left to right, right to left, and from top to bottom; the most common being from left to right.
But there´s a trick to it though, you can check out which way the animal or person signs are looking. So basically if the snake is looking to the right you read from right to left, and vice versa.
Any hieroglyphs inside a cartouche represent a king or pharaoh.
You can get yourself a cartouche with your name written inside in hieroglyphs as a necklace pendant or bracelet (or however you want to use it). It´s quite popular and a nice conversation starter too!
Or if you just want to learn how to write someone´s name in hieroglyphics, get your drawing pencils out and practice using the simple alphabet.
