•Big trifold (You can find these at CVS, Walgreens, etc.)
•Chalkboard spray paint
All you have to do is take your trifold and spray paint it. Depending on how thick your trifold is, you may want to do several layers to make sure.
I know this is a simple DIY, and you may want more ideas, but I promise you guys, I will have more wedding DIY's up in the future, but I think having them up at separate times is a better idea because you have more time to work on the one DIY, and some other things for the wedding, and then come to a new DIY project when you're ready, vs. doing it all in one day, but if you're new, I also do regular DIY's, and those usually have five DIY ideas in one post, so just click the search bar and type in "diy" and a million posts will pop up, and maybe some of them will give you more ideas.
Good luck! Kisses to my neonators!
