I bought my toddler a pack of 4x6 cards (cheap and can be found anywhere!) I prefer to buy the "plain" ones, but lined ones work too. I can keep some of these handy in my purse, her tote bag, or above the fridge for any "bored" moment, I am able to give her a few pieces of it, and crayons (or pens) and let her do art to her heart's content. Then, I convert these into "postcards" to send to friends and relatives. The size is perfect, and it is very easy to draw a line down the backside, and address as a normal postcard--postage is the same too!
Personal photos can be used to create unique postcards to send to friends and family. This is a page about make your own photo postcards.
