This book boasts high quality 340gsm multi media paper. This new mixed media sketching format from Sennelier was tested by our own Liz Carlson on her recent travels. Liz found both the size and the paper to be exceptional, taking wet and dry media well. The compact closed size is 6x4 and the longest possible layout reaches to 6x38.5. This style is great for landscape or narrative work succinct to a project, thought or location.
