HELP! Magic Water Painting Paper?
I’ve heard and used of this paper called Magic Paper where you can paint with water and it dries after a few seconds so you can paint again.
Its really helpful for practicing calligraphy, and also for kids.
The only problem is…. I CANT FIND IT ANYWHERE!
Ive searched google and looked at all websites in the first 5 pages. Nothing! You can buy it in America, Japan and China but I need to ship it to the UK
Does anyone know of this paper? And can anyone tell me if its available in the UK?
Thanks, 10 points to person who knows if you can get it in the UK
book shops sometimes
..art shops
i got some for my birthday from a art shop 
good luck
