Welcome from NY and I advise...Put each row together with a Baste Stitch...if your machine doesn't have one then the longest stitch your machine has which is usually a 6. This way if your seams don't match you don't have to rip but just pull your baste sting out and reallign and try again with baste stitch...once all OK just sew over the baste stitch with your regular stitch...SEW EASY no ripping
