Quilting should be an enjoyment and not a Barrier. It seems that you won't let yourself begin the process cause you know you will not be able to start and finish due to other commitments and that is why everything else is complete ( the pattern, choice of fabrics, machines ready, desk clean, etc.) You know these things will be completed and done (OCD). To start a project the OCD gets in your way so you don't. It's not a bad thing, it's just a thing and you will need to either tell yourself, "so I may not be able to complete it today, or I may not get it all done," but it is started. To comply with yourself , when some of it is started and not able to complete, then neatly put it away for the next day. Even if it's 2 hours a day to work on it, at least you started. But the putting it away neatly and organized will satisfy the part of you that won't. It's the fear of not being able to complete it is what's stopping you. Good Luck to you, hopefully we'll see that quilt, no matter how good or bad it may be. We don't police it here, just support and help.
