Create flyers and put them out in local grocery stores, fabric stores, etc. Make small talk while in line in stores with the person behind of in front of you and hand them a card with your info on it if you find they are into it. Contact local churches and ask if they have sew groups in there church. Pass flyers in your own neighborhood asking if anyone sews/quilts and that you are looking for a quilting buddy. Talk to folks you already know and ask them if they know anyone that sews and/or quilts and if they do ask for there contact info or hand them a card and ask if they would mind making contact with that person to introduce you to them.
