Custom lines is that an oxymoron?

I've been thinking a lot about my jewellery and what makes my beach glass pieces stand out when compared to other beach glass work. I also have been thinking about the responses I got over the summer as I'm preparing for my two upcoming shows(NGB Studio Tour and the Gift Giving show - www.giftgivingshow.com) . So the combined question at hand? It's actually two questions: how do I stand out and be remembered (which leads to repeat customers and custom orders) and how to make it simpler to do so?

Up until now, not only have I always created one-of-kind pieces but only one-offs too. Well. The solution to my questions: lines (beachshuk, perfect pendants, whispy - http://lindseyfair.ca/index.cfm?page=collection). I have created a few lines of work (although each piece will always be unique because each piece of glass is unique), so that people can order something and have an idea of what they are getting, they can compare items in my booth and most of all, when showcasing my work to other artists I have a line that will stand out.

I'm not sure if this is the best strategy, but here's to trying. I'll keep you posted. Let me know what you think about it.
