Did you do last week's 'freeze frame' *blink*? Now, instead of an event, write about a place. Be short, direct, accurate, no flowery language necessary. And you don't have to be describing Niagara Falls or the Grand Canyon. Maybe you just want to talk about your kitchen counter or the path out to your mailbox. In any case, pay close attention and try to include observations from the perspective of all your senses. If you're still enjoying yourself, change tense and go again.
And, don't forget, you can send your results to me at authorbethneff (at) gmail (dot) com and I might comment or post (if you want me to.) Keep it fun!
