I made a novel that you can hide your seed phrase in.

The idea was pretty simple.

There are 24 chapters in the book and each chapter has every word from the BIP39 word list appear once.

So, lets say the 11th word of your seed phrase is 'jaguar' you would go to chapter 11 find that word and mark it somehow, then move onto chapter 12 to find the 12th word of your seed phrase.

You can find the script I used and the pdf to print it yourself on github
