The stiff with starch quilt will not be a problem, in fact your quilter may thank you for that! But the wrinkles could be quilted in. I would try to press them out if you can. Maybe just spritz that area with a little water and press. Give your LAQ a heads up about them so she or he can watch for them. If you are having an all over design done (like a panto) and your quilter does not have robotics they will be working from the back of the machine and will not see the wrinkles while quilting. If your are doing a custom or the quilter has robotics or is doing a free hand all over then she or he will be working from the front and should spot them and be able to smooth them out before quilting over them. I think you should try and do your best to get them out before delivering the top.
