Can anyone tell me where I can buy/oder large size parchment or aged texture paper? Likely A1 or A2 size. I ask this is because I found it is available in some online printing service like zazzle, so I guess there must be someone making it. What I am thinking is to print in only black color to make my work looks better, not to print the background textures. But all the result I found from internet were all in A4 size.
