I don't use watercolors much, but in the mediums I do use paper is a big deal. The first marker paper I got was terrible and I eventually started blaming myself for not being able to get markers to work like other people could.

I have strong feelings about Rendr paper because it was the first good paper I used. Suddenly, so many things I'd been trying to do with my markers, pens and pencils just started to work. It's not the best for markers and I think I am going to eventually switch to just using loose cardstock.

There are a lot of ins and outs to using different mediums together and how they work with paper. I used to wind up with a mess every time I tried to ink a sketch.
