Point: There are only 26 English letters, but there are countless word combinations. So the point is not to practice copybooks, but to master the link method of circles. You can buy a book, which is more important than copybook. Because I have mastered the essentials, I can write 26 letters together, which means that all English words can be written.
My English teacher writes beautifully on the blackboard. I just watched her write, wondering how she was doing in Lian Bi, and then I understood. Personally, I think it's ok. I didn't buy a copybook. Good luck.
