Recently, one of my friends mistook my Copic-drawn background as watercolor painting.  This was probably because it had no outlines.  
That gave me the idea to try to emulate a watercolor style, with my markers:  Copics, Prismacolor Premier, ShinHan Art Touch Twin, and Tombow markers.  Basically, I'm omitting outlines, and defining shapes with shading.  When I think about it, that's what I should have been doing all along.  But for some reason, I just didn't think that way until I thought of emulating watercolors.  I guess those nice inked outlines make the color-shading side of my brain, lazy.    Which is also strange, because omitting the step to ink my outlines, makes the drawing process so much easier!  It's a lot faster to just go from drawing to coloring, without stopping at that meticulous, strenuous inking step.  

Now I've come to a need to choose a proper underdrawing medium.  I thought I had found gold, with the marker which I actually thought was a wasted purchase.  The store that I bought Copic FYR1 ("Fluorescent Orange") from, did not allow the testing of markers before buying.  So I didn't know it was totally not the color I needed, until I got home (or at least, out of the store, with it purchased).  Purely by mistake, I discovered that my scanner (Canon MP460) cannot detect Copic FYR1.  It was a fantastic marker to use for underdrawings, and made my first experiment in using markers to emulate a watercolor style, work so well.  But then I started using it for drawings which included blues and greens in the color pallet.  ~_~;  Apparently, when Copic FYR1 is overlapped with blue or green colors, it becomes detectable to my scanner.  So, then I tried returning to pencil underdrawings.  But I can't just erase the pencil marks after coloring, because alcohol inks make pencil marks stain into paper.  So today I tried erasing my pencil underdrawing right before coloring, but leaving just enough for me to see what areas to color.  Even though the remaining pencil marks were too faint to properly keep the places of where to color or leave blank (and I did make some mistakes that needed white-out), those faint pencil marks were still made dark by the alcohol ink in the artist illustration markers.  ;~;  Here I was, trying for no outlines!  This just would not do.  

So now I am on the hunt for a proper technique for underdrawings.  Perhaps I should try a photo pencil.  Perhaps there's another way to use the materials I already have.  The experiments continue...
