From cake bakers to caterers, to planners, hundreds of new weddings means thousands of new dollars in the local economy.
"I expect a lot more business," said Remo Borracchini, owner of Borracchini's Bakery in Seattle.
Borracchini's Bakery has been making wedding cakes for same sex-couples for years. Though the bakers are in the midst of Christmas baking, the owner says the shop can still meet a Sunday deadline for a wedding cake.
"We may still get an order, because one thing about us: if you need a cake, we'll make it for you," he said.
Duos Catering is already seeing bookings for same-sex weddings. The money is a welcome boon for the owners who are getting ready to open a new restaurant. But with gay ownership, the boost from the passage of Referendum 74 is more than financial.
"It's history in the making," said co-owner Benjamin Jury, who is planning his own wedding. "It's pretty neat to be, to actually see it happen."
Executive chef Will Yee is just grateful for the opportunity.
"We never thought this would happen, honestly. I've been together with my partner almost 10 years - it'll be 10 years in January - there's nothing yet," he said.
Diane Ruff and Amanda Butzberger have been together nearly 10 years. In that time, they've officially become domestic partners, had a commitment ceremony, done everything they could to profess their love for one another.
Now, they're getting married.
"Thanks to Washington state voters, we finally get a chance to ... have a definition that everybody can understand, and we don't have to try to define it anymore," Butzberger said.
