Postcards are nearly as lovely as handwritten letters even though you are a bit restricted with the amount of waffle you’re allowed on them (plus they aren’t very private unless you put them in an envelope). But anyway we didn’t want to leave them out because frankly they are fab and fun and sometimes just weird (always a great challenge to send the strangest picture postcard you can find from a place you’re staying) so here’s a link to The Postcard Traders Association. They do a much more thorough job when it comes to everything postcards.
Likewise with stamps. The plain old 1st and 2nd class stamps are great but a “pretty” one does add a little beauty and intrigue to the envelope. Again, if you’re really into your stamps there are loads of websites but here’s a link to Stamp World and Royal Mail websites which are good places to visit.
