My mother was one of 8 brothers and sisters and this was standard stuff for them at Christmas when they got older and married (with lots and lots of kids). Works great!

Re: posting, every national postal system has it's 'mail-by' dates - the overseas date for Britain is usually end of October, which I've always faithfully ignored. Usually if I get something in the post by end November it can get to N. America in time for Christmas.
