I made my first Heidi Swapp calendar last year during a BPS class, A Year To Remember 2007, taught by Heidi Swapp and loved it. I had so much fun doing it, I decided to make another one for this year. I like having documentation of the year's happenings, it comes in handy sometimes. I would also consider making one of these calendars for an expectant mom to document her pregnancy or for the birth of a new baby. If you want to start the calendar with the beginning of a pregnancy and it isn't January, then just cover the area on the calendar where the month is printed with embellishments and use stamps etc. and start with whatever month you want.
I like the clear pages in between the months for layouts. After 12 months, you have a completed scrapbook!
