On the far left is the Pentel mechanical pencil I use drawing the foundations. Its got a nice rubber grip which in addition to being nice to hold, doesn't roll off the slanted board I draw on. You won't see any pencil in the above picture as it's all erased after the ink is put down.
In the middle is a Faber-Castell Pitt indian ink Brush pen. It's. This used to be regulated to drawing panel borders, but it's become my new favourite tool. It's actually a sort of pen/brush hybrid, combining advantages of both. The tip is flexible and now that I have a bit more control over it enables you to vary the line width a good bit, but the tip is a good bit firmer than the normal brushes I use thus being easier to control and it also doesn't need to be dipped in ink constantly so its quicker to use.
On the right is a Rotring pigmented ink pen. I just picked this up a couple of weeks ago in Bradbury Graphics in Belfast. They had just found an old batch out the back and were selling them for £1.99 so thought I'd try one. Its got a nice flow to it, but with all pens it's only really got one width to the line.
I'll probably end up going back to the brush as the pen line can often come out a little monotonous (if that word can apply here) when I'm not careful. I'll do a post and show the brushes/ink I normally use another time.
What I'd really like is a brush pen that comes in a variation of sizes so that I could get in to the small areas without having to worry about applying to much pressure and ruining the piece. If anyone knows if these exist let me know :D
