I had a sit down with my 'calendars' this week and passed on the Maddesigns calendar to Mark so the website could be updated. You'll find the link here
I broke things down into Home (birthdays, personal travel, hair appointments and the like) MadDesigns (teaching engagements, call for entries and the like) and Book Milestones (design, bead, illustrate, ship) They are color coded and I can at any moment look at 1, 2 or all 3 of them to see who it all works together.
And through the brilliance of iCloud, I can update on my phone, iPad, or iMac and all of my calendars are in synch. I still however keep the cute little snow and graham desk calendar for a visual and artistic reference to the date.
