I just wrote an extensive and detailed post with questions for anyone who has exchanged through Brother. However, I previewed the post and somehow it disappeared. I do not have time to re-write as my husband is wondering why it has taken me nearly 45 minutes to "send an email" ( he has no understanding of applique as an obsession-although he does try.) So I am asking for anyone who has had to exchange a machine provide feedback about the process and what you had to do for Brother to approve you for an exchange. As I wrote in the other post I am pretty discouraged about my well loved machine not functioning appropriately. It was purchased in March and has been serviced once. It will not hold tension despite the efforts of the service tech and tips that I have tried from forums on this issue. Believe me when I say that I have tried everything. Please share your knowledge!!! Thanks!
