Every week, we pose a challenge: using any word of the day from this week, create a perfect tweet, otherwise known as a twoosh. If we like it, your tweet will appear on our blog. For the past few weeks, in honor of back-to-school season, we’ve been giving away a full set of Pocket Posh Word Power dictionaries to a randomly chosen winner. This is the last week!

And the lucky winner is. . .

Congrats to @welblech, aka Michel Welblech!

In addition, here are our favorite perfect tweets from this week.

Thanks to everyone for playing! Next week you’ll have another chance to perfect your word of the day perfect tweets. To get the word of the day, just follow us on Twitter, like us on Facebook, or subscribe via email.
