Anonymous / what kind of sketchbooks are those? is that acrylic paint in them? i can't find a sketchbook that will lie flat and handle paints like that ):

Hey there. I’m using a leuchtturm1917 dotted notebook. Yep it’s acrylic, although I’m not actually sure why the acrylic isn’t buckling the paper as it does usually with thin paper… Good luck finding something that suits your needs!
