 How about the check sum?

 Works fine👍🏻—this #bitcoin key is the 256-bit integer, so no checksum needed

 So it works every time?

You would have to enter each 1 or 0 into a wallet manually to get any use out of it right? Aren't you afraid of making a mistake?

 Next is to build a signer or address generator to do it automatically ala seedsigner or crux/maix, but in the meantime I made a spreadsheet to help translate the private key into public keys/npub/addresses—you can use any tool to do this and of course #offline is best

Converting 256 bits into digital form is easier than you expect—took about two or three minutes.  You quadruple check, to be sure, as you would for anything of value, and of course you have backups

 Its interesting as it looks like you start with the backup, then move into the digital space. 

Pretty cool!

How about a passphrase? I guess that would have to be on a separate piece.
