Buy the dice here: https://store.coinkite.com/store/seedplate

What I’d do: roll a die. If odd, write a 1, if even write 0. Repeat this process until you get 11 bits. Then look up the corresponding word in the bip 39 wordlist (https://en.bitcoin.it/wiki/Seed_phrase).

Repeat this process to get as many words as desired. 12 is almost certainly too many for a password/phrase on a seed phrase.

Alternatively, you can just buy a cold card and let it generate its own seed phrase and take the first few/several words for a passphrase.

Even better, did you know you can let the cold card generate a seed phrase and then roll die to mix your own entropy into the machine-based entropy?
