Avoiding Warped Boards // Adventures in Bookbinding

In this video I discuss and demonstrate how materials such as paper, card, board, cloth and leather interact with each other when laminated with wet adhesive. Understanding how materials behave is essential to moving from copying what you have been taught to being able to design your own books. This topic is particularly important for obtaining flat stable boards. These videos are only possible thanks to the support of Patreons, and if you are able, your support would be greatly appreciated. https://www.patreon.com/DASBookbinding I understand not everyone wants to use Patreon.

The tools and materials I use can be purchased from specialist suppliers and manufacturers in my suppliers list.
