No more moves like that unless you plan to stick by what you said! It is great that she gave in and said she wanted to work on the M, but if she had not done that...THEN where would you be? If you were calling her. Bluff, it won't work the second time around. And, I'm thinking it was mostly hot air b/c you were watching her to see what she did.
Do not use threats, bluffs, or ultimatiives unless you carry through, or your stitch will be worse than it is now!
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
