hi! I have a question, is it technically cheating if you write an idea for each of the options before hand?  It doesn’t say it’s against the rules so do I do it?

Well, the list of topics is public and the rules say "Making everything from scratch is not mandatory, but if you do you get to be extra proud of yourself at the end!"

"Everything" includes the idea itself and after all, if after reading the topic list an idea pops into your head you (or anyone else) can't stop yourself from thinking about it.
