Monogram themed bridal shower??

If you like monogrammed items, that sounds like a great idea. I'm not sure how you would do a registry for something like that though since must custom item sites like Etsy don't offer registries.

I think the best option would be to just say something on the invitation like "help the bride embrace her new last name by gifting her a monogrammed or personalized item from your favorite shop!" Honestly, a bunch of southern women are already going to have their favorite place to shop for monogrammed items, they probably don't need a registry anyway lol. The Etsy account idea sounds great, but if someone forgets to delete something they've already purchased and end up with two, you typically can't return something that's customized.

While I was searching for invitation wording to see if this is something others have done, I found some really cute invitations that said "join us for monograms and mimosas," super cute for a theme and I think that'll make it even more clear that you want customized items.

We have an Amazon registry, but my mom sent out little recipe cards with our invites for guests to write down a recipe and bring it back. Then my mom will put them all in a book for me. She is getting married after I am (second marriage) and I'm going to either do an alcohol or succulent themed shower, since she doesn't need gifts but loves both those things!

If you like the monogrammed items, then yes, go for it. We don't really need things, but we'd like to upgrade some items.

Other ideas/themes not "registry gift":

Stock the Bar Shower - if you like to drink or host, this is great

Recipe for Marriage Shower (as mentioned above, everyone just shares their favorite recipes)

Remodel Shower - a friend of mine did this, it was interesting.. they were remodeling their bathroom and people brought them gift cards for Lowes/Home Depot, etc

Kitchen Shower - they'd bring about anything kitchen related, great if you like to cook

House Plant Shower - everyone would bring you a plant, have a green thumb for this one haha

Create A Date Shower - people can either write down date ideas or bring you items to go along with the dates (ex: for a movie/dinner date bring gift cards for each)

Hobby Shower - is there something you/FH love to do? Fishing, hiking, cooking, movie night, etc

I had to come back and find your post because, while working on our Amazon registry, I noticed that they have lots of personalized items, more than I ever expected. Maybe you could consider an Amazon registry for your monogram themed shower!
