An airplane chased by a lovey-dovey contrail, a heart-shaped lock with skeleton key, two little lovebirds sitting on a wire -- these garland-style cards simply require ribbon, cord, or twine. Mixing patterned and solid-color papers helps create contrast and adds visual interest.

What better way to communicate your love to your main squeeze than with an accordion-fold card? A quick print, cut, and crease is all it takes to make a card with a trio of hearts, a big LOVE, or sweet old XOXOs.

When you really care, you just have to get all up in their faces -- and these pop-up cards pack a (loving) punch.

A crush can be more powerful than a locomotive. It can also be as sweet as a hand-delivered note, or as cheerily optimistic as an upturned mailbox flag. These clip art illustrations require a few simple cuts and a couple of pieces of tape. The little envelope acts as a card within a card, containing a secret love note or special gift card.
