I also use paint mixing sticks as shelf markers in my school library. I usually number each one and the students and I find them very easy to use.
These sticks will be great for the students to use to hold their place on the shelf when they take a book down to look at it and then they will be able to return the book to it's correct place. I am going to spray paint the sticks by grade level and attach a student's picture and ID bar code onto the back of a stick so substitutes can easily check out the books to students they don't know.
Used for plant markers and as intended
better than the free ones you get a the paint store.
I used these sticks to make the handles on wedding fan programs. These are also a good buy for crafters looking to buy in bulk.
