Often an important decision is what is the type-face and that controls the whole look of the book, and then of course you're involved in collaborating not only with an illustrator, but a designer. I've been lucky to work with a designer who's also a friend of mine, Douglas Martin. Douglas chose the type and designed the pages for a book of poems I did called The Mighty Slide. I like the look of the pages in that book very much. Unfortunately not too many other people seemed to like the poems themselves, so you may not have heard of it. The Mighty Slide - see if you can find it.
