Every July I start my new planner for the up coming year, this year I am doing a 15 month calendar. I decided to go with a bigger format in an effort to keep up with my growing birthday lists and card events. I switched from a smaller 5x7 format and went to a big A4 size! Originally I printed calander from a microsoft template, and was very excited it when it only took two hours and 70 sheets of 40# paper. THEN I noticed it was for 2012! I decided 20.00 for a new pretty one was worth the investment! I plan how many birthday/occasions cards I need about a month ahead of time, having all the birthdays and occasions marked in the calender makes this easy my average month averages about 60 birthday cards alone!! On the Daily pages I note everything I mail out of here, cards, packages, sales, it all; gets logged. some of this counts at tax time. If you participate in swaps and challenges and have pen pals around the world, this type of organization becomes invaluable!!
