Ok, throwing out an idea or suggestion here.
A friend of ours "made" a calendar. She took muliple pictures of us and had them collaged on the top sheet. Some were definitely related to the month....Halloween shots in Oct, Pool/beach in June, etc. Important dates (birthdays, anniversaries, etc.) were noted on specific days each month. She had Jasc software which included a calendar option. She printed ONE calendar and decided to have the rest professionaly printed because it took FOREVER to print one calendar. Any way having a full design already done decreased the cost of layout, etc. So maybe this idea could be a consideration? I thought a collage of yorkie pictures on each month would be easier than selecting ONE per month. Either way, I'd be interested.
PS I love the school bus picture....definitely a September contender.
