I like a large meander for patterns I can't decide a quilting pattern for. As others have said put in a new sharp needle and get your tension set before starting. Meander to me is a non-pattern and does not distract from the quilt design. To help to get a consistant meander size, decide on an object you are familiar with such as golf ball, tennis ball etc. for the loop sizes....this really helps to keep the meander consistant over the quilt.
