The prop-makers are called upon to make everything from sheep-sized beach towels, to bath toys for Timmy, and even a table for a magic scene.
Prop maker Helen Javes said: "Everything is made by hand, so it is very intricate.
"Even the table legs have been turned by hand to get the right shape."
But the job of the prop-maker is not without risks. The slicing of fingers from sharp knives, and burns from hot glue are all in a day's work.
