Sales kit

I am still working on a sales kit to take into stores. I have a bunch of inventory but I am not sure how much of it to use. I've been really focusing all of my creative energy on crochet jewlery. I have really liked the results so far. But I also have a bunch of beaded and wire wrapped stuff.

Do I include some of the old stuff in the kit thinking that I may want to go back to it? Or do I just focus on my newer works?

I'd appreciate some opinions.
