Hi Janie, Even though everyone is different, this is what has worked well for me. I've had good results, using waterbrushes with watercolor paint/watercolor pencils/water-soluble pencils with Arteza Watercolor 140 lb paper, for quick sketches and occasionally finished art. Depending on the subject, I might use the smoother back-side or the rougher front-side of the paper. I created this watercolor Blue Jay painting on Arteza W/C paper, smooth-side. I haven't used watercolor brush pens yet, but they look really interesting, I have to say. As for erasers and general erasing on w/c paper, I like using a Faber-Castell kneaded eraser and for tight spots or details, I like the Mono Zero Eraser pen with the round tip, cut into a wedge shape. For general erasing, I reach for the Staedtler Mars Plastic eraser. I hope this helped a little!
For the last couple of months, I got back into painting but with watercolor brush pens. I’ve never tried them and I LOVE them! So I started with cheap Arteza watercolor paper and was watching a watercolorist talk about paper so I got some Arches cold press 140lb paper. It was great until I decided to do some sketching on it and of course with a cheap eraser, it did not work out well. So tonight, I decide to get back out the Arteza paper and I’m in love with it. 140lb. It’s so smooth for the brush pens. Have any of you tried this paper? I’m a little baffled as to why I like the cheap paper better besides the fact that the cheap eraser works better with it. I’ve got some Arches hot press paper coming and I’m sure that will be smoother but idk why this is bothering me. Lol. Ok and what kind of eraser should I get? One that doesn’t leave a residue? Do any of you use brush pens? I did get regular watercolors but I’m loving these brush pens so much that I feel like I’m cheating. Lol
