I have the frame all set up and the ledge across the top that holds the pantogram is really bowed down. The lady I bought it from had only used it as a short frame where I have it set up to quilt full sized quilts. I am wondering if this is going to mess up the shape of the pantograph as it is transfered to the quilt. I haven't used the frame yet...anything I should know? Likes or dislikes about the frame?
