I drew this Hogwarts-inspired diagram years ago, as an aide for English classes to help students learn the names of rooms in a house. …And of course all houses have turrets and potion cupboards… But I like the drawing, so I gave it a sepia tint and put it on RedBubble for anyone who’d like a copy. Might also be fun for people who like colouring-in. ;)

/ Tuesday 25, April, 2017If you get this from RedBubble in ‘fine art’ print, the paper they use is like watercolour paper, and can take almost *anything*. Colouring pencils (soft with lots of pigment) would obviously be fine, but watercolours (with not *too* much water) and markers would work fine as well – and be transparent, so you’d still see the lines.
