I have given up trying to sew for Christmas. I have learned when it stresses you it then has become work not what we all "enjoy" doing. I now sew for birthdays.
I think your grandkids would love having grandma with them to do small special things with them. Cookies, a story read,watch their favorite movie with them etc.
In a time that has become more materialistic I think we all need to step back and find the simple again.
