This 7 x 10 sketchbook fits easily in a shoulder bag or book bag; the wire binding is big enough to clip a Sharpie on the inside; the paper is good quality and doesn't make caterpillars or end-blots even when you draw with cheap pens; makes good pen lines into spectacular pen lines! The thick covers are sturdy enough you can draw standing up in a gallery or sprawled on a couch in front of the TV.
