I don't know exactly how you would go about doing this, but the community I live in just had a "Gingerbread Market" sale this past weekend in the clubhouse (and surrounding parking area). Basically, it was for people like you that sell crafty or boutique like items. I think anyone could get a booth at the show (not sure if it cost anything). You may want to look into some of the communities in your area or ask the chamber of commerce if there are any of those type festivals or anything going on in the next couple of months. They tend to pop up around this time so that people can get gifts for the holidays.
I also know that there are some stores popping up that will sell your items on eBay for you. They, of course, take a cut of your earnings, but if you don't have the time for it, that may be an option. I've seen these types of stores in strip malls sometimes. You may just Google it or look in the yellow pages to see if there are any of those around.
One other thought is to see if there is an existing boutique in your area that would be willing to give you some shelf space to sell what you have left or just buy it from you so they can sell it.
That's about all of the ideas I have...I hope you're able to get something for your stuff. And good luck with being a SAHM! I have been at home for almost 2 years now and I wouldn't change a thing. :-)
