Never ever feel that your quilting is not good enough for a competition. You will only get discouraged. There are many Domestic Machine quilted quilters out there that do breathtaking work, you can do the same, it just takes lots of practice. Any entry should acknowledge anyone that worked on it at all, ie.; person who pieced it, the pattern designer, and quilter, if it was quilted by hand, by your machine, or by a Longarmer. Just make sure everyone involved gets credit
