Offline paper wallets - can I make my own


I want to bring my ADA offline into cold storage.
How can I make a paper wallet offline?

So far I see it is in development. Any expectations on release date?
btw I saw the graphics designs for the paper wallet, awesome, but would have been nice to make a simple vanilla paper wallet generator first then beautify later.

If I am still facing a wait of months for this, then is there a way I can create a key pair offline.
I can manually create a view/deposit QR code myself.
