Yes, it's a "headlace," NOT "headless," or even "head lice!" This is the way creative minds work... see something that looks like a possibility and try it! This green and gold decoration (a necklace in a previous life) turned into a headlace today when I saw that it matched what I was wearing. It had happy adventures going around town on my head, winking and shining at passersby.
This is the way my husband, Bob, works, too. Instead of thinking, "I need a hammer," he tells himself, "I need something to drive this nail." (Maybe that's why he can fix anything with a bubblegum and a piece of string!)
So when you're writing, let your imagination put things together in ways that may not have been done before. Perhaps a necklace could be a wristlace, an anklelace, or even a waistlace! (That's "belt" for more traditional thinkers.) Letting yourself see common things in new ways frees up your mind and your creativity, which is valuable, because after all, no one can write like you!
So tell us, what have you used in a way that it was not originally intended? How did it turn out?
