I have a calendar that I carry around--when it's closed it's 8 1/2" x 11", big enough so I can write quite a bit. Previously I tried to use gCal on my iPhone, but that wasn't working so well because I couldn't see ahead. I've also seen those huge wall calendars in kitchens--which seem great, but then do you also have a second calendar for when you leave the house? I feel like I need a place in my kitchen...maybe a magnetic board/dry erase board with the calendar, lists, etc.
Anyway, just looking for ideas and thoughts on what works for others. My DD starts 5-day preschool this fall, and I need to get my act together. (I'm working on meal planning, shopping lists, and all that stuff, too...)
