Yes, you will get there! It can happen because you get better that the techniques or you just decide that those few imperfections make it unique and special because you made them. We all strive to make our points perfect, quilting exact and cutting straight but we are human beings who are not perfect. An incorrect breath when cutting or stitching can make a little error that often no one sees except us. Keep quilting and enjoy learning the skills you need to know to do the kind of quilting you enjoy.
Even experienced quilters make mistakes and put in a block side-ways or mess up points now and again. We have seen those postings on the Board. Give yourself some grace and don't lose the joy of the colors, patterns and process. Could it be that you are being too hard on yourself? Chin up and move ahead with a smile.
