I always had a heck of a time keeping my seams straight. Finally someone took pity on me and told me my trouble was caused because I watched the needle instead of the fabric. Once I started to pay attention to where my fabric was going under the front of the presser foot instead of at the needle my seams straightened right up. Once you get the hang of sewing you'll be able to make a quilt on any working machine - no matter how old it is.
