If this is the first block you've ever done--wow! You did great!! Yes, there is room for improvement but try making another block and see if it isn't better. Sometimes, no matter how "perfect" you think you are doing it, there is something that just doesn't come together. Unlike some others here, I am not a fan of Jennie Doan. There are some of her designs that just don't come together. To me, it seems in her striving to make quilting quick and easy, she sometimes misses the finer issues of piecing. Plus, have you ever seen her rip anything out? The tutorials are designed to make it look easy! Another post recommends Eleanor Burns and I enjoy her tutorials. She is entertaining but also has an expectation of her work turning out well. If you have a local quilt guild, you may pick up some useful tips by attending a meeting or simply finding another experienced quilter who is willing to help you when you have issues such as those lost points. And believe me, those lost points will stay with you no matter how long you have been quilting! Keep at it. This is one hobby that can be very rewarding as well as frustrating.
