I use Cambria font at least size 55 but will go up to 65 or 70 if I can. I break up the phrases and take up as much room on one sheet of paper as I can. I try to fit at least one verse on one 8.5x11 sheet of paper. It usually can be done. You just have to mess with the font and margins until it all fits. :)
Camille puts her pages in sheet protectors. I've heard other people recommend not doing that because of potential glare (and it saves room in your binder). I guess you could use the non shiny sheet protectors. So far I've just punched holes in the paper and used them that way.
I don't put them in my binder anymore because the music stand we have in our Primary room is very weak and does not hold much weight at all. Plus I found it difficult to flip through to each song in a short amount of time. Now I post all the Opening Exercises songs for that day up on the front chalkboard with a magnet. It seems to work well and I don't have to fuss with all that page turning!
