At the beginning of each year, I make it a point to write down friends and family members' birthdays and special occasions, e.g. anniversaries, graduations, Valentine's Day, on my planner. Then I set a reminder to mail out a card the week before the occasion, so that it arrives on time.
These are some tools and supplies I personally use that inspires me to put pen to paper. I hope it inspires you to love the art of the handwritten note.
