Looting the cake stalls in Ardougne will gain you 16xp per loot. Beware of the Guards patrolling the market area and also the Baker. If you get caught, simply kill the guard or run away.
Level 20-40
At level 20 you can stick with stealing from the cake stall if your prefer, but i would advise Moving over to the silk stalls, also located in Ardougne. You now gain 24xp per loot.

The master Farmer.
He lives in Draynor market square, and right above Ardy. Your inventory will fill up quickly with all types of seeds. Bank them and sell them at the G.E for some cash. You gain 43xp per loot.
If you want, you could do this to 99. You would make around 100m.

Use the same picture as the Cake stall.
Level 65-71 Sorcerers garden -Use the same picture as the Cake stall.
Summer room.
This is how you get there, the building in the picture.
If you have completed the Prince Ali Rescue quest, speak to Osman outside of the Al-Kharid Palace. He will explain how to get started with the sorcerers garden mini game.
You will need a pestle and mortar and several empty beer glasses. From Al-Kharid bank go south-east behind the palace,you will find a small house there. Inside the house, speak to the Apprentice, persuade her to teleport you to the Sorcerer's Garden. You will only need to persuade the Apprentice once. The next time you go to her, just click the 'teleport option'.
Try and keep your weight to a minimum and wear boots of lightness + spotted/spottier cape if possible.
Now the aim of the game is to navigate around the summer garden without being seen by the elementals.
Once you reach the tree which holds the Sq'uirk fruits, pick it and you will be teleported outside of the garden.
Repeat until you have roughly around 244 fruits. Using your pestal and mortar, make the fruits into sq'uirk juice. For thieving experience, you must take the glasses of Squ'irk Juice to Osman. You will receive 3k exp for each juice you give him.
Level 71-99

Pyramid plunder is by far the quickest way to reach lvl 99 thieve. Please be aware that Pyramid plunder is not safe at all, if you die you will lose everything.
