The leaves are glued just above the block. As soon as one with watercolor paints it (watercolor painted with water) then the paper curls very strong- not as strong as normal 80gr paper but still very strong :(
I actually thought there is special watercolor paper that but it does not seem to have an extra ....
But what is very good, the Radiereigenschaften. Bleier can erase very well and it remains almost nothing. That's why I use it now just as a sketchpad: / For the price but of course not so great ....
