Speaking from the LAQ side, It is very easy to bump a quilt when a client tells me, No hurry, no rush, don't have a set date I need it by. If someone comes to me while the "no hurry" quilt is in que needing something done quickly, I will definitely bump the non deadline quilt. Your new LAQ is not a mind reader. She has no idea you wanted to gift the quilt in May. By all means, please give her the opportunity to do right by you and tell her that your intention was to gift the quilt and you really need to have it done within the next week or two. I am a part time quilter so I let people know that it usually takes me two weeks to complete a quilt as I only quilt on weekends. Most of my hand guided custom jobs take a good 16 to 20 hours of actual quilting time or more depending on density of quilting and how elaborate the designs are. This does not include design time and marking time if marking is involved. Also measuring and racking.
If your LAQ is doing an all over or computer generated quilt job it can be done in a day.
So please call her and let her know what your plans are. She should not be upset with you at all. This is simply a case of inadequate communication on both parts.
