Your paper uses double lines. Our school uses three lines. Will this lead to confusion?

The average classroom uses multiple styles of paper and we want to teach students how to write on all of them. Our double lines are designed to help students master handwriting and develop an internal sense of size and letter placement that eases the transition to other styles of paper. Our double line paper eliminates line confusion. Directions are plain and clear. The baseline keeps the writing straight, and the midline controls the size of the letters.
