I would keep going with it - everyone has to start somewhere. Those ladies might be really good now but they didn't get good without doing some quilting! ;) If you don't think you can handle it, maybe save it for when you feel more confident in your skills...but if it were me I'd just keep plugging away and don't let the other ladies intimidate you. You might even be able to use this project to connect with them and find yourself with a couple new friends who'd love to help teach you!
