Another thing to consider when selecting a quilt pattern, is what is your piecing style. Do you work quickly or do you take your time? Do you want to challenge yourself or are you content with your abilities? Are you a perfectionist or a "good enough" quilter? Do you care how long it takes? How big is the project? Do you get bored when you make the same block over and over again? Selecting a quilt, that doesn't match your piecing-style increases the odds of it becoming a UFO.
Your piecing style will also develop and change with experience.
