Lifelines

Well I have learned the importance of a life line. I got overly excited to get started on Gale by Anne Hanson and decided against stitch markers and a lifeline cause it was going so well. I just had to rip it out because I could not figure out where I went wrong. I am using Fantasia II colorway by purewool and I am loving it. So when I restart I will add a lifeline here and there so I do not loose all of my work. How long would it take me to finish otherwise.
