You will get better as long as you want to improve.
With quilting its important to be precise in cutting, stitching, pressing, and keeping everything squared up
everytime as you piece. And its important to use good fabric. Cheap thin fabric can make a quilt look poorly made. Quilting is not for one who is nonchalant about being precise. It takes time to learn all the aspects of piecing and theres always new tecniques to learn.
Good luck and have fun.
