Just in the nick of time (the evening before the ceremony), Theresa and Jon found a white 1959 Cadillac convertible with red leather interior to rent. Friends decorated the car with soup cans and paper fans in the wedding's color palette. The fans are made by accordion-folding 10-inch-square pieces of tissue paper and cinching them with red twine, which also tied it all to the car.

Bride Cheree created light-pink card-stock "chargers" printed with her and Jeff's names and wedding date. The trumpeter on the place card (which doubles as a menu) hints at Jeff's love of music, while a card invites guests to save room for dessert. Just behind it: a port glass with a chocolate and a monogrammed tag balanced on top. For the centerpiece, red, pink, and orange dahlias, zinnias, and roses form a neat dome.

Bride Lauren's bouquet overflows with blooms, including dahlias, tulips, ranunculus, maidenhair fern, nerines, scabiosa, and viburnum foliage.

The groomsmen in this wedding held in New York City wore boutonnieres which combine flowers found in the bride's bouquet, like scabiosa and eucalyptus fruit, and are bound in red-and-white seersucker to match the color palette of the day.

A different ranch animal presides over each table, set with mismatched plates and napkins for a rustic, intimate, family-dinner vibe at this rustic wedding held in Napa. Bride Satoko bought them, along with the votive holders and centerpiece vessels, at tag sales, antiques stores, Goodwill, and the Alameda Flea Market.

Jean's bouquet includes olive branches, seeded eucalyptus, red dahlias, orange zinnias, and red celosia, complementing the color palette and maintaining a casual feel. A handkerchief that belonged to the groom's maternal grandmother is wrapped around the bouquet.

Bride Cheree gives a peek of color with red Stuart Weitzman open-toe pumps.

Groom Craig's cherry boutonniere is embellished with striped ribbon.

For their monogram, Haylee and Franklin use nautical flags that stand for their first initials. Invitations are letterpressed in navy and red, and envelopes are lined in yellow.

Bride Cara's mother handled all the floral elements. Cara and her mom brainstormed, then assembled the bouquets the morning of the wedding. The bouquet of red carnations and roses fits perfectly into the palette of red and white.

Jean and Devin's artistic flair is reflected in the decor of their wedding. How did they create the homespun feeling at the reception? At the seated dinner, yarn is wrapped around Mason jars that have greenery and red flowers in them and are set down the center of the long tables.

Couple Satoko and Alex hung bags on a clothesline for each wedding guest to take. Inside each bag is a program and recipe book featuring the caterer's recipes, among others.

Bride Lauren's self-designed stationery suite boasts a unique finishing touch: vintage Lewis and Clark stamps that represented the couple's cross-country romance.

This red cooler glass favor is reminiscent of a racetrack souvenir. In its box lined with blue tissue paper and sealed with a ribbon and a patterned sticker, it goes perfectly with the horse racing theme of Theresa and Jon's wedding in Saratoga Springs, New York.

Bride Cheree wears a Carolina Herrera lace gown and carries a bouquet of red, pink, and orange ranunculus with a single tiny golden bee -- one of the motifs the bride often uses in her work as a stationer -- perched among the flowers. The embroidered hankie, her something blue, is a gift from Martha Stewart Weddings editorial director Darcy Miller.

The men in Jean and Devin's wedding don boutonnieres featuring assorted red flowers and a few small leaves.

Bride Lauren handcrafted her guest book out of envelopes, into which guests were asked to tuck notes and well wishes.

Cheree, bride and owner of Cheree Berry Paper, a stationery and graphic-design company, created invitations with creamy envelopes addressed in swirls of red calligraphy, with the words "love mail" printed in the corner. Different printing techniques (including engraving and letterpress), unexpected touches (the origami chart of St. Louis attractions), and fanciful details (the bee on the reply card) give a richly layered feel. Cheree, deeming a palette of reds, oranges, and pinks "too perfect," laced it with robin's-egg blue.

When the guests arrive for Alanna and Benjamin's ceremony, they find programs with their names inscribed in opaque white ink, or gouache, which show up beautifully on the red paper.

Colorful tea canisters hold loose red and yellow flowers at Satoko and Alex's rustic wedding in Napa.

Slices of red velvet cake wrapped in papers stand in for Jeff's groom's cake. Bride Cheree crafted the crimson garlands in the background by spray-painting foam balls and stringing them on fishing line.

Designed by bride Casey and made by Lana of Lana's Sweets, the three-tiered cake is dotted in red icing and finished off with a cake topper that mimicked Alfred Eisenstaedt's famous photo of a sailor and nurse embracing in Times Square on V-J Day. The topper was found on eBay and perfectly brought together the thematic elements of the wedding.

Following a family tradition, bride Lauren stitched her mother and mother-in-law's initials onto vintage handkerchiefs and presented them to the women before the ceremony.

In addition to fresh summer fruit and ice cream, guests at this New York City wedding are treated to coconut-flecked red velvet cake with sweet buttercream frosting for dessert; the cake, like many elements in the celebration, bears stripes in the wedding's principal hues: red and white.
