Your quilt is beautiful!!!! I would take the plunge and go for it on the long arm!!! I would plan out my quilting first like was mentioned on a practice piece and if you are feeling comfortable with it, pedal to the metal!!!! Don't they all have the stitch regulators on them??? If so, that is 50% of the battle right there, and not having to wrangle the quilt another 25% factored in, you will have help for questions right there.....I'm thinking it's a go :D :D :D
