I have one set of hand drums from Periopole which are color coded by size. I liked this system and thought for one moment what it would take to paint the drums. But, I opted for color-coded labels. Each size is assigned a color and number.
8" drum = #1 Purple
10" drum = #2 Blue
12" drum = #3 Green
14" drum = #4 Yellow
16" drum = #5 Red
The labels are printed on standard mailing labels measuring 1" by 2 5/8". I borrowed some clear book tape from my librarian to add an extra layer of protection from peeling.
I'm very happy with this project and the kids were excited to see the fancy labels. No one has dared try to peel the tape off yet! They saw my face and knew I was serious about losing their drum if I saw them destroying my new labels! If you would like to use these labels in your classroom, I have the file uploaded to my Teachers Pay Teachers store. The link is below. Happy drumming!
