1. You can use a 13 word/passphrase
2. You can use steganography
3. You can use multiple ways/locations to store each word
4. You can make a nice story containing 12 words. Read here: #1260936
5. Read my guides:

The most important thing: use the 3 levels stash

I like to think about it as single points of failure.

If you have 24 words and split them in half (storing 12 in one place and 12 in another), you have two places where you can lose all your coins. That sounds scary.

Everyone has a different threat model, but I assume that losing my own coins is my most likely threat, while theft still needs to be defended against but is not as likely.

So, some options are putting all 24 words in the same place or making more copies so that you can suffer a loss to one set of words and not lose your coins. You might also consider putting seed words in steel or perhaps saving a digital copy on a CD.

In the long run I'd encourage you to investigate multisig options, as they have gotten a lot easier to do and can provide some redundancy.

personally I would not get overly fancy, just stamp seed words onto non-corrodeable metal (paper burns) and store in a single, ultrasafe place, e.g. hole in the ground where you definitely won't forget the location.

border wallet.

I have made several backups, and to prevent them from falling into the wrong hands, I have encrypted the information using a word-based encryption technique. This is to ensure that, should they ever fall into the wrong hands, no one will be able to tell which words the document contains, and to keep my seed safe.

Have your seed backed up in multiple locations is very smart move.
I've test many of the metal stamping tools, but the one that stands apart from all of them is MicroSeed, you can store your 12 or 24 mnemonic seed phrase on a single 1inch washer, which is nearly insvible to the naked eye. And you can store it by screwing it at the back of one of your machines in the house, or even in your tool box amongst other washers. I highly recommend MicroSeed (https://microseed.io/?ref=UNRUGGABLE), you can also use the discount code UNRUGGABLE and save yourself 5%.
