This big, buoyant bouquet of tulips, ranunculus, astrantias, and Japanese anemones, bound with a pale green ribbon, will brighten any celebration.

To turn a snapshot of you and your fiance into a swoon-worthy statement, give it a Warhol effect: Make black-and-white copies of your favorite photo on 8 1/2-by-11-inch sheets of paper, and then fill in a few details with colored pencils (stick to accenting with just two shades). Fold each one in quarters, secure with a sticker (we used Layer Cake Shop’s round labels), and address the front; no envelope required.

What’s not to love about a handy pocket, whether it’s hidden within the folds of a dress or organizing all the pieces of your stationery? Regas NY’s “Modern Mint” makes it easy to inform guests about multipart events, as you can simply slip the details for the rehearsal dinner or next-day brunch inside. If you’re hosting a single-date affair, use the flap for your reception and RSVP cards instead.

Trade "I do"s with your groom in a faux field of glorious yellow flowers. It’s one garden setting that you don’t need a green thumb to cultivate.

Make a splash with two delicious libations: a booze-free Honeydew-Jasmine Seltzer (far left), which gets its green tint from melon balls, and a Lemon Drop (left) that contains vodka, limoncello, and fresh-squeezed lemon juice. For a modern approach to bridesmaid dresses, go with yellow and green in a couple of coordinating styles. Ditch the wrist version, and wear a blossom as a brooch instead. A vibrant tree peony is especially gorgeous.

Mood-boosting tulips, clustered by variety (from left: French, parrot, and double-petal), cast a golden glow in Bauer Pottery Company vases (bauerpottery.com). If you live near a good flower market, you or a pal can DIY this project. Buy the blossoms -- at least 30 per vessel -- a day before (just keep them cool and give them plenty of water). Tying the knot in another season? Go for dahlias in summer and amaryllis in fall or winter.

Armed with spray paint and peel-off letters, you can transform a chalkboard into a guidepost. First, protect the edges with painters’ tape, prime the black background, and then apply yellow paint. After it’s dry, stick on the letters and spray with green. Once that dries, pull off letters and tape, cover the front with paper and tape, and finish by painting the edges.
