The call is open internationally (but you do need to post your original card to the UK if selected).
Click here for all the details on how to submit. The deadline is stated as 21 April, but I bet they'd still look at your entry if you were only a day or so late. Anyway, your card should be a quick and easy 20 minute make, so you've got loads of time to make a card or even two within the deadline ;)
Go for it - just remember to include stamping!
