Block letters filled in with No. 2 pencil scratches? Sound familiar? Notes to your BFF in Math class, the heading on today's To Do list... Nice chunky enclosed images just need to be filled in. Enjoy the young, light-hearted look of SNF Sketchy and SNF Sketchbook...Sketchy is a little taller and thinner, while Sketchbook is solid and stocky. Two must-haves if you live on this planet, and you've ever held a pencil in your hand and had even a bit of space on a paper to fill up.
