This does take some effort on my part and unfortunately, I usually wait until the last minute to mail them so they do not always arrive on or before the holiday.
Sure, it would be cheaper and less wasteful to send e-cards or email, but there is something so personal and special about receiving a real card in the mailbox via snail-mail. Besides, at least half of the recipients of my cards do not have email. :-) Handwritten letters are always well-received and looked forward to so I do try to include a short note detailing our recent adventures, no matter how dull and routine they may seem to us.I know the simple words will brighten someone else's day.
This Valentines Day, I created cards from magazine pictures I'd collected. I find the cutting, arranging and pasting and picking out the right card for each person or family when I'm finished very relaxing and enjoyable. They are nothing fancy but created and sent with love!
Keeping in touch by sending little cards and letters seem to shorten the distance between us all and is a special ritual that I don't do nearly often enough!
