"Problem: Because my items are meant to be worn, I really need to have them modelled."
I spoke with my younger brother's fiance and four work friends and all were happy to be my models. They would represent my focus customer base very well, I think. I'm still working out what payment options I will offer, but am leaning towards giving them a choice between: a) a discount on future jewelry purchases, or b) free items from a selection of jewelry. I mentioned the possibility of this choice and each seemed more than happy with it (though none expected payment). I'm very fortunate to have people like them in my life.
"Problem: Promoting my items and finding more venues."
I spoke with one of my friends (and model-to-be) and she gave me a number of avenues to look into, both in specific festivals/events and locations. She definitely gave me a lot to look into and said she's willing to offer up more as well as going on hunting expeditions for stores that might be willing to carry my jewelry.
