UPDATE:
The first lot of letters (6) have now been sent! (picture blurred to protect addresses :))
For the 5 international winners (USA and AUS), the letters containing your stickers should be with you in about a week's time, give or take a few days (depending on your respective postal systems)
For our UK winner, the letter should be with you in 1-2 days, according to royal mail 1st class post :)
A reminder for the remaining 3 winners: I need your deets! otherwise I can't send the stickers to you!
Thanks again to everyone for taking part!
This has to be a regular thing.
@Montoya what do you think?
I would enjoy doing this again! :D
Thinking about doing the next one end of September / start of October :)
