Hello klenae. No, watermarks are no problem at all (and should never be because it's to protect your work). "No things on it" means pencils ect. Best greetings to you !
Dear member.... I'm the owner of this group and apologize for some delays here and there. This is due to the fact that I'm handling the group alone and have some health problems and moreover a lot other life things to manage. Will do my best in future !
