Take a deep breath! Now another one. And now another one. You have a big project sitting in front of you. I would follow the tutorial closely that MSQC has online. She makes it sound easy enough. I have found her tutorials very clear and easy over time. Her's are the best. With all the curves going slowly is the best advice I can give you. Be confident that you can do it and don't think about other things for Christmas. Everything will fall into place as it should. If you only get the top ready for the holiday gift so be it. She can return it to you for finishing. Try not to cramp yourself up with to much in the short time before Christmas.
