Relax. If you don't have time, you don't have time. Christmas is more about the wonderful memories we make anyways. If you're set on giving stockings to the grandchildren....buy the red pre-made ones (a couple of $ in K-Mart/Walmart, etc), and put their initials on them. Won't take long and you'll cross that off your list.
I started quilts last February and mailed 8 of them this morning. I still have 2 quillows to do and if they get done, they get done. We'll still celebrate Christmas and they'll get quillows next year

Deep breaths...give yourself a break
