Where can I hang my diplomas and certificates I live in an apartment?

I've heard it said not to hang your diplomas up in your home because it looks tacky; however, I personally don't buy into that. I've made some accomplishments and I am very proud of that. Looking at my diplomas encourage me to continue to be a go getter in other endeavors. Now, as I stated before, I live in a one bedroom apartment (900 sq. feet). I did have some certificates by the entrance/exit door, but now I'm thinking of purchasing a desk so I can make an area of my living room look like an office section and I can hang my certificates there. Suggestions please!
