Octopus T-ShirtHurray, hurray! Today, the 21th of june 2014, it's International T-Shirt Day. What that really means and what's its origin, is not entirely clear. But a party is a party, and that should be celebrated.

How do we do that? Two things. First you use the hashtag #TSHIRTTHEWORLD in every tweet or post you send today. In addition, you hul yourself in one of Cardvibes's T-Shirts, which of course you buy in one of Cardvibes's T-Shirts shops.

Have fun!
