Yes I did them with my daughter and we just used boxes and went to the dollar tree and mixed the wrapping paper on each box different and then used cardboard and did the letters the same way or you can go to Walmart and get the wood letters and paint them and then you can hang them up in the baby room after you are done with the boxes
I did boxes like these, I worked at a fast food restaurant so I just took the fry boxes to use, wrapped in some gift wrap, and cut the letters out of cardboard and painted them.
I was at my doctors and she said her daughter did that and the name she wanted didn’t win. Idk how it works but just make sure you’re okay with whatever outcome of the name
