I know they have moved onto a new prompt but here's my illustration for beneath. My son and I read an old favorite this week, Hug by Jez Alborough. I must have never looked at how the illustrations were done before and I was surprised to see that it said Prismacolor markers, a medium you do not see much anymore in books. So this week in my studio before I left I wanted to play around and here's the result.
Sarah, I tried to blend them with the pencil blender (because I don't have a marker blender) like you described but it didn't work, you're going to have to refresh my memory next meeting.
