I'd keep giving them away - what about your husband's workplace? neighbors? church mates? people in any other community groups to which you belong? Perhaps your local shelters will take them? But you'd have to investigate that. Many don't take open or homemade items due to food safety concerns. I wouldn't sell them unless you feel you've perfected your product (or are close to that point) and are compliant with all of your local business and department of health regulations/licensing requirements. And, in the process of giving them away, I'd also ask people to fill out short feedback forms on their like and dislikes. Feedback is the best way to perfect your product. Hope that helps.
P.S. I'm glad to see another cookie convert who's loving the craft of decorating!
