Help with flat work schooling

[Only way is up]

This year I plan to have a lot of flat work lessons, I’m looking to buy some books or DVDs to give me a helping hand. Does anyone know of any good books or DVDs that would keep my horse interested in training?

What schooling books have you used or good tips?

Thank You
