A good guide for anyone who wants to give BTC as a gift, the paper is cheap, and the process is not too complicated. Although I personally have never used Jaxx wallet, I remember they have some problems in the past as mjglqw mentioned. But I don't think that's a reason to avoid using it for smaller amounts of few mBTC.

Only problem I see is in fact that mobile wallets should not be used for long-term storage, due to various security risks who have recently posted on this forum as well. Apple with its smartphone operating system as well as Android shows too many security flaws, and repairing them takes too long or is not possible at all.

So I would add another step, which is to introduce new owners to secure storage options such as cold wallets or hardware wallets. It would be an ideal gift if we can give BTC on a hardware wallet, but I guess the price is still a limiting factor for that.
