My first pieced quilt was a bit on the wonky side, but is still loved by the owner. Not to worry, a lot of times this is in cutting the initial pieces or from joining seams that aren't quite consistent yet. It really depends on what it looks like, to be honest. If the rows are noticeably off----and it bothers you, you may want to change it up a bit. Please know that quilts are rarely if ever perfect and go easier on yourself. Enjoy the process. OH and you may have a local free quilters group at your local library if you need some hands on assistance. =)
