Penelope, I wouldn't sell off anything just yet. Don't be hasty.
PR and marketing advice is pretty easy. Just look how much you have gotten from these forums.
Down the road, if you are as successful as you hope to be, your biggest challenge will be keeping up production. When production comes into play, you may need to hire people to "hand make" each doll, dresses, etc. Cash Flow becomes a problem at this point and it's at this point, if you want Cash Infusion for labor & materials, that a partial sell of your business "May" be appropriate. Try to avoid it though.
Remember, the value of your business is not just tangible, but intangibles also. Your stories have value even though they are not yet sold. You are creating equity in your business through your hard work and creativity. The most fun about a business is creating value from thin air. A doll is a doll is a doll, but your dolls have more value because they are magical and you have created a world in which they live and breath.
Don't sell yourself short. Follow advice in these forums on marketing, linking, etc and I'm sure you will do great at the
PR.
