I have an unending well of sentimentality for Polaroids, whether they're really coming back or not.

Cue the Polaroid Notes ($15), a set of 20 notecards and envelopes. The images are sweet and dreamy, which is how I think we tend to remember Polaroids (rather than washed out and abrupt).

And if you still want to make your own Polaroids via modern technology, try the website Rollip or download Poladroid.
