I tweaked the calendar I was inspired to make by this piece of mail into a stand-alone perpetual calendar that I can keep on my desk.
I adhered two pieces of 8-1/2″ x 11″ cardstock together to create the base.
Why don’t you make one and give it to your child’s teacher on the first day of school? It makes a great gift and it’s a great tool for teachers to use to record the students’ birthdays!
