Minted!

I used minted for STDs, but postcards, not magnets. I added my website to the STD. They have a proofing process where you can put in the comments what you want, they send you a proof and you can send back approval or any additional edits you want. I used them for my invitations as well and both times everything went well!

I used Minted for my save the dates and they were magnets but only one picture. You can filter on minted and here are magnets with three pictures

You can also add your own text box on some of them and include what you want. Or sometimes it can be placed on the back

There’s a place at the top that says “special requests.” Just type in there exactly what you want and where on the STD. They’ll create it for you and send you the proof to be approved before you order.

We used minted for cards and had them printed on the back. We have used minted for everything, and they really work hard to incorporate whatever you write in the “special requests” box. Utilize it, and request to add your website, ask to see the proof and you should be ok

Thanks for the advice everyone!
