This round, we'd like to do things a little differently and treat one pretty postal pal to a special gift. We're putting together a colourful collection of stationery surprises to send to one of our participants.

It's really simple to enter, when your monochromatic mail is ready to be posted, please snap a photo and share it on Instagram or in an IG story, making sure to tag us @prettypostal and use the hashtag #monomailsent. You can also email it to us. (When posting on Instagram, make sure to cover or obscure any addresses.)

Once we receive your completed mail image, we'll enter your name into the giveaway draw. Only one entry per person, so no need to send us oodles of pictures (unless you really want to!) Images must be of completed mail, not process shots - we want to confirm that you've sent mail, not that you're working on it, but we're always happy to see process shots as you create your one of a kind mail!

We'll also be running a second stationery giveaway on our IG page, so follow @prettypostal and keep your eyes out for the upcoming giveaway post.
