My planner has saved me many times...just this past Christmas I did something a little different....I photo copied or printed any recipes I would be using for Christmas 2010 and put them in the notebook so everything was at my fingertips when I needed it.
I did any cookie/candy recipes
Recipes for Christmas Eve dinner
Christmas breakfast too
I worked great...just grabbed the notebook and was ready.
I also created a master grocery list from the recipes and bought ingredients over several weeks...easier on the budget!
