Poised to replace “something new” faster than a seasoned bridesmaid can hot-glue lace to a mason jar, “something DIY” is a new benchmark for Pinterest-happy brides-to-be. But when it comes to the flowers for a ceremony or reception, some professional oversight can help. “It just takes the edge off,” says Alice Rossiter, local founder of the recently launched Alice’s Table, a floral arrangement class service that hosts private how-to’s for bridal parties and showers, charity galas and book clubs, as well as $65-per-person public events at bars. The 90-minute classes include step-by-step instruction and a cocktail pairing, plus an arrangement and vase for each guest to take home. Rossiter, who also offers premade deliveries and has DIY kit deliveries in the works, says that the goal is to have attendees have fun while learning a new skill. “The whole business is about spreading joy,” she says. “It’s assisted DIY.”

On Choosing Flowers

“Hydrangeas are my favorite flower, mostly because you get a lot of coverage for one stem of hydrangeas. … Hydrangeas are expensive, but they are the same price as a rose, so I’d rather have that coverage and throw in two roses.”

On Presentation

“We use the English hand-tie technique. … It’s the bridal bouquet in a vase. Most people in the U.S. think a bridal bouquet is only for a bridal bouquet, but really, they look beautiful in a vase. And it’s an easy way to quickly arrange.”

On Staying Power

“The way to kill your flowers the fastest is to leave the leaves in the water. The leaves are down in the water, which means that bacteria grows, and that kills them. … And plant food is there for a reason; you should use it.”
