Fun and effective
Even though I'm nearly an adult (just turned 50), the idea of a coloring book to improve my handwriting is very appealing. This book is not just fun; it actually works. I take a lot of notes on the job and it has never really been an option for me to go back and read them later. I've just done it so I could admire whatever pen, ink, and paper combination I was fond of at the moment and draw tiny pictures of molluscs in the margins. The cool thing about this book is that it has a bunch of exercises to help practice particular motions, like loops and things, and then it has coloring pages that reinforce the exercises. I highly recommend it, even if you are one of those weirdos with naturally legible handwriting.
