The company threw a similar stunt in London last July, where singles decorated their bags with doodles and 140-character fun facts about themselves.

“I actually met my boyfriend through ‘Size Matters’ three years ago, and we moved to Austin together,” says Soletti.

“We all have our dating deal-breakers — whether it’s not wanting to have children or you have certain religious preferences — so this is a formula for success, because you know what you’re getting.” Hagans, who’s hit the “Size Matters,” “Beauty & the Geek” and “Childproof” nights, now swears by speed-dating parties.

And it’s a great chance to see if you both have chemistry.” There’s even less pressure at Paper Bag Speed Dating, in theory, because no one is going to judge you by your face.

“I always thought speed-dating was like that awkward scene from ‘The 40-Year-Old Virgin,’ and I didn’t want anything to do with that,” says Sandra Rodriguez, 33, from Astoria. It’s going to be a really funny way to break the ice.” Still, some participants point out that the bag won’t do much to disguise a potential partner’s features — or their figure.

“You go hang out with one girl, but the whole time you’re wondering if the other hot girl in the corner is watching you,” admits Ben Roth, 25, from Midwood.

“I’m not proud of it, but it happens.” Amber Soletti, who spent four years looking for love in the city, agrees.

But participants had such a blast hooking up at Loveflutter’s anti-Tinder party that the hosts are bringing it across the pond, beginning with NYC — and not a minute too soon, say singles.

“Dating here is definitely more complicated than anywhere else,” says Alida Brandenburg, 30, who moved to Williamsburg from San Francisco a year ago.

The gents are measured at the door to ensure they stand at least 6-foot-1.

Other mixers include “Rescue Me” to find firemen, and “Childproof” for partners who’d prefer to avoid the parent trap.

“The hardest thing is not giving up when you keep putting yourself out there, and continue going on these terrible dates,” she says.
