I am an art teacher in Bangkok and I am looking for a very large,strong, durable yet affordable paper to draw a huge mural for my students. The students in school will then use this as therapeutic mindfulness time to colour using pencil colours or felt tip pens.

One of the most popular, and durable, drawing papers available is Stonehenge, which is also available in 50" wide rolls. Finding Stonehenge in Bangkok will be challenging. However, if you click on the "where to buy" link at the bottom right side of this link below, it will list where this paper is available worldwide. Many of those resellers offer international shipping.
