Do you have any tricks you use to quickly create a memorable impression when describing lots of characters? I'm having a challenge in cementing characteristics to make the several people immediatley memorable. I'd hate to resort to, "Jeff was tall and skinny, with dark hair", and "Jeff ran his lanky fingers through his short, dark hair." If I only had a couple characters, I could trade off, or use the action sentence technique to create a fuller picture of Jeff. Easy-peasy. However, I have twelve military recruits that I'm introducing within the scope of a 30 page chapter. One is the main character and we've known him since the beginning. I try to introduce the others in smaller sections, such as, "Tyla's strawberry blonde hair reached down to her uniform collar." and "Amelia slinked like a cat and struck an informal pose next to the commander, hips canted to the side." In another section, I have the main character interact with three others, each with characteristic mentions as above. Then another section, I do some more characters. My dilemma is that using this sort of technique allows me to only give one stroke of description for each character at a time, AND only when the natural flow of the interactions permit. For example, I describe Carmen as twisting her long brown hair into a bun, she shakes another's hand firmly, and says a few things about sports. These are such small brush strokes that I'm concerned that the reader A) won't get a good picture of Carmen being a jock, nice looking, medium build, assertive, possessed, etc. B) won't remember anything concrete about Carmen from such a fleeting and subtle action. Were it only a few characters, I could work in more characterizations to firmly establish an image of each player in the reader s mind. But I've got a whole bunch. I'm doing my best to reiterate some characterizations, but don't want to say, "his red hair" more than once, maybe twice. Any techniques you use to quickly establish a memorable image when introducing multiple characters?
