Hi there, Stabstitcher!
Line is no longer in development. Check out Adobe Illustrator Draw here for an updated app with more options: Drawing and vector design app | Download Adobe Illustrator Draw
Let me know if that helps!
Thanks, I'll give it a try. I have both Sketcher and Illustrator Draw on my iPad. The ink is charging at the moment, so experimentation will be delayed. I'll get back to you once I've made the attempt.
