I'm currently using a Daler Rowney marker pad combined with Sharpie markers for sketching web layouts / graphic design ideas. Which seems to work a treat. I've been reading up on layout paper and like the idea of using it to save time by tracing over previously drawn sketches. I find I can trace through Daler Rowney marker paper without too much hassle when using Sharpie markers, but has anyone tried using markers and layout paper? Or would markers most likely soak through several sheets of it?
