We quite understand that you can't time travel to make some valentines. (Please tweet us if we are mistaken, for it would be utterly cool to receive a time travel tweet.) What we mean is, visit Vintage Holiday Crafts, The Graphics Fairy, Karen's Whimsey, & The Vintage Moth to download images you like (there are many different styles of vintage) & then put together some cards. (Or get everything ready & then have children or friends make some cards.) If you'll be hand-delivering, these doily envelopes are pretty, easy, & inexpensive.
