Your story is very familiar. We started a quilting group and have "never nevers" (never even owned a sewing machine) to very experienced quilters. Fortunately a few if the newbies took it upon themselves to take a few basic classes at the LQS and they are progressing with their skills. The experienced quilters offer help and advice along the way. It is so important that newbies take a basic class so they understand what quilting is all about. Two should not do all the sewing, quilting etc. I agree give them a list of needs/supplies and help as needed. You will weed out the non quilters soon enough. Good luck
