Your star is beautiful! Too often we are the hardest on ourselves and I think you are being too hard on yourself. There are many quilters here who want everything to be "perfect" but as you continue to quilt you will find that perfection is not all it is cracked up to be and in face it is impossible to achieve. Even if you have a few wrinkles and bubbles along the way getting a top quilted hides a lot of sins. I love your fabrics and completly want to see this as a finished quilt.
