Way back in January, while the Northern hemisphere was in a deep freeze, we challenged our pretty post-ers to send juicy, colourful, tropical mail. And, oh my, did they ever deliver!

Gloriously vibrant mail filled with pineapples, palm trees and pina coladas brightened up mailboxes from coast to coast and across the world!

We love seeing all the different interpretations of each theme and the variety of techniques each swapper uses to express it. Here are a handful of our favourite images shared on Instagram. Check out the #prettypostalswap tag for more!

@melgodecki got colourful with pretty papers and embellishments

@postcardsfromindia played with a combo of watercolours and embossing

@pen.cell pulled out all the stamps!

@fleursjosephine combined interesting materials and textures

@shirleyshirleybobirley captured the joy of a big pile of colourful mail with your name on it!

Looks like fun, right? Hope you'll join us for our next snail mail adventure.
