I just scanned most of the responses, so I hope I am not repeating a suggestion. We have a small craft/quilt consignment shop in out town. She seems to be getting more and more people coming in and is doing pretty well. Check and see if you have a local consignment shop that may be looking for quilts or handmade items. You may have some luck going in this direction. This shop seems to do very well in the fall while everyone is looking for Christmas gifts.
Good Luck....I also have 3 girls!! I stayed home with them also and it was a blessing!
