I would guess it depends on how busy she is (and a good long-armer will probably by busy). If she puts you in line with all the others she has and does yours when yours comes up, it could take awhile. But if that is the case, she should be honest and say, "I have x-number of quilts ahead of yours, so it will be approx. x-number of weeks until I get to yours." As a custom hand quilter that takes about 3-6 weeks to hand quilt a quilt, I can give my customers an approx. time, but always let them know how many quilts are already in line before theirs. Right now, with my daughter's wedding in less than two weeks, they know all quilting is on hold for now. It all boils down to honest communication. If you ask for it in a month and she knows there is no way she can do it that soon, she should be honest. Occasionally I will skip a place in line if someone has a small baby quilt they want done by a certain date for a baby shower, since they are small and won't mess up the time line that much. Communication is key.
