S wasn’t going to have favors but H really wanted there to be peanuts on the table, since we had that for our wedding and it’s a Chinese pun for good luck.
We bought tiny ziplocks and roasted peanuts (some honey-glazed) and bagged them. S and DIL bought stickers and little mesh/tulle bags. Each guest got one at their seat—none were left behind at end of evening. (The venue & coordinator made sure it was all laid out properly—guests were all enjoying appetizers & cocktails.)
The peanuts on the wedding table would have been terrible luck for my S who is very allergic!
The last wedding we went to was on the shore about 45 north of Boston, woopie pies in a nice box. It was at a resort, all guests were out of town, and staying over.
Well, they did ask about allergies and no one mentioned any, plus it was an outdoor wedding and reception.
I would personally not want anything engraved with the event/couples name with the exception of a food item.
I’ll also say that if there was a favor on the table and it wasn’t something I really wanted I might take it just because I wouldn’t want the host to feel bad their mementos were left behind. But I might toss it when. I got home.
You can get customized m & m’s. I’d love that 
True—many nick-nacks do get tossed as so many of us have too much “stuff” and are working to declutter. That’s why we really prefer consumables. My nephew and his bride gave personalized magnets with guest 1st names. It was original and we have it on our metal dresser and washer/dryer—it was unbreskable (brass) and reminds us of the event.
My niece gave metal keychains — 1/2 hearts for each member of a couple. I’m not sure anyone saved them after wedding.
I’ve heard of “flip-flops” as favors, so guests can take off uncomfortable footwear and swap for flip-flops (in wedding colors, of course). Couple specifies assortment of sizes as well as colors. Seems like you’d end up with extras—I guess you could donate them.

The last wedding I went to also had a flip flop basket which I really appreciated! Old navy $1 days.
Anyone who goes into a thrift store has seen the glasses with the etched names on them; a big waste of money.
My niece had a cookie/sweets table cellophane bags so guests could select & take an assortment of goodies with them when they left the reception.
Always something consumable, and put it on the table above the plate. Nobody needs more stuff and it often gets left behind.
For son’s wedding , a friend dipped long pretzels in white chocolate. For daughter’s wedding we ordered Mackinac Island fudge, 2 bite size pieces per box.
My town has a tea company, and they have these small, very pretty, tins of wedding tea. I believe they can be personalized too.
I always feel sorry for “Ashley and Chris” who agonized over their wedding favors, only to have their guests haul the champagne glass, cute frisbie, personalized candy dish, or adorable chalk board end up at Goodwill.
The Goodwill near me had to set up an entire display of “wedding souvenirs”-- I guess for folks whose names are Ashley and Chris who love stuff personalized in a semi-artistic/weird font.
Do something edible. The crystal, wood, plastic, fabric, glass stuff- no matter how adorable, becomes someone’s problem to dispose of in an environmentally OK way. Don’t do that to your guests!
Signed- Ashley and Chris, October 2024, a day we will never forget but was just another Sunday you spent in the car while wearing Spanx and pantyhose
Yeah, my sister and BIL gave everyone small tins of tea as a wedding favor.
We’re seeing couples make donations to nonprofits in lieu of favors and including a note to that effect in the wedding programs.
My nephew and his bride gave coasters with their initials. Light weight and easy to transport.
Have gotten donuts or candy as well.
Agree that consumable is very nice.
I saw wedding coasters propping up a wobbly table at an eatery at OHare airport last week. Everyone who passed smiled knowingly… Quick and useful way to dump your wedding paraphernalia by dropping it at the airport on the way home from the wedding!
Some folks just aren’t sentimental!
We gave boxes of Krispy Kreme donuts [delivered so they were fairly fresh]. People seemed happy 
We did the customized M&M’s for S21’s grad party and everyone loved those too.
Back in 1984 for our wedding favor we gave a box with 2 Godiva chocolates in it. Easy to buy, easy to distribute, everybody took theirs, and they looked pretty (gold box).
they still sell them
