Over the course of the year any time my cats did anything memorable, I'd scribble down a note or a sketch. I redrew a bunch of the poses to best get the idea across. I post them up on my cork board over my drafting table as reference.
Then I pencil a little mock-up book on regular computer paper to check my layout. I ended up changing the page order slightly so it flowed better.
I divide my Bristol board pages into sections of 6. I only use 3 pages of Bristol to draw my 16 page book because the final book is half size. (4.25 x 5.5)
After the pages are penciled, I ink them with a 0 brush and Koh-i-nohr Rapidograph ink.
I ink the text with a .08 Micron and erase my pencil lines.
