We started out just making them for friends as well, that expanded and I made a separate facebook page -- mainly because not all of my friends were interested in seeing all of my cookies all of the time. I ordered business cards that doubled as an ingredients list and made sure that there were good pictures on them. During holidays I would leave cookies for my neighbors with a card from us and a copy of the business card behind. I hung up our business card on local bulletin boards (gas stations/libraries etc). I made it a point to donate cookies at least once a month to different local charities, even if they couldn't provide a tax receipt. I did a couple of farmers markets and donated the leftover cookies with branding still attached to the local hospice house...
We took a hit the first few months in profit -- but it's all a business marketing expense -- it's normal for a new business to have negative income for a little while as you establish your footprint -- don't be afraid to show others what you can do -- seeing and then tasting is believing with decorated cookies! Good luck!
