The subject recently came up of how difficult it sometimes is to find fresh ways to describe your characters. How many ways can you describe blonde hair, or a short beard, someone who is tall, or short?
It is difficult at times. But not impossible. I think the main reason we often struggle with this is not that "we've seen it all before" but because we are so rushed that it short circuits our creativity. I know it does mine. I try to find writing time in the morning but sometimes I'll be panicking inside thinking "Oh no! I only have 20 minutes before I have to leave to go do A, B, and C." I'm so busy being stressed about my to-do's that well-deep creativity is squashed. Just like we can't be distracted and have genuine heart-felt time with the Lord, we also need concentration time for our writing.
It is also good to make your description do double duty---both offer a bit of physical description and tell something about your character at the same time.
Here's an example. I usually end up re-reading Zane Grey's Forlorn River once a year or so, and am in the process of doing that now.
In a scene in this book, one man describes another man this way:
"that pasty-faced potato-head on a whip handle!"
ROTFL!!! There is absolutely no doubt in the reader's mind either about the physical image of this man nor the speaker's opinion of him. And in just a handful of words.
It makes me smile so much when I read it, I can't help but imagine that Mr. Grey smiled as he wrote it. 8-)
So we can find fresh ways to describe our characters, and do double duty too.
