Handling 3- and 4-page songs
Use a 3-hole punch on the center pages. Cut down some of the margin on the outer page or pages so that when you tape the pages to the center pages of the song, they will clear the binder rings. Use a sturdy folder (or make your own for free from cereal boxes and packing tape) in the front and back of the 3-ring binder. Attach a string to keep each folder at an angle for easier viewing, instead of splayed out widely. You may keep the folders closed if not playing the 3 or 4 page pieces. See the photos below for clarification. My binder is white, the heavy-duty folders are black, and the strings are yellow.
