It's ok to make mistakes, that's how we learn. Keep going and working on your quilts and you will be making beautiful ones too! Everyone starts out a beginner, the trick is to keep trying and learning. And if you have any questions or problems, someone on this site would be more than happy to help you. Some more experienced quilters on this site have partnered with beginners. Maybe if you ask for a mentor, someone near you will help you! All you have to do is ask!
