I know that a lot of teachers have saved transparency sheets and in the digital age of the projector don't use them. That means that somewhere they're sitting in a stock room closet or in the back of a desk drawer. I asked around for old transparency sheets (saving myself a trip to Office Max) and got a ton for free! Printing onto them using a laser printer is really quite easy and when you tape them onto a bulletin board (or staple, depending on where you're putting them) the clean lines you get look wonderful! All the pictures you see here from my room are transparency sheets on high gloss foam core. Check the gallery below for pictures from my room and from my church.
I created the red quote poster (seen above) at the beginning of the year and love how it looks hanging in my room. The words by Carl Orff really sum up what I think about teaching music and so when I decided to make this visual I wanted it to look professional and clean. The transparency sheets were easy to print, cut out, and tape up (I used double sided tape and put it on the back of the sheets). So easy that I continued to use them when I made a couple other bulletin board for my room. The only downside is that the "extra" clear border can sometimes cause a glare when light hits it at a certain angle. My advice is that you be aware of where you place these so that little people look up to see the words and not the reflection/glare of overhead lights
