Organizing this merry making stuff has become on of my favorite holiday traditions. This year there are nine different little gifts or activities for us to do sometime before Christmas. I don't go in numerical order and sometimes we might do a whole bunch at once.
Last year, I made everything green, so this year I managed to use every color but green. I put together tags that just got stapled onto envelopes and lunch bags along with some colorful matching striped paper.
I also made two planner pages. I write out what each number is in case I forget (which I usually do) and roughly estimate the days we will open it. I also made a notes page to keep track of anything else that I might need to keep track of.
