I hope I'm understanding your question correctly, but here's a few points that came to mind...
Using pen and ink is fairly tricky, because it can give you a variety of line thickness, depending on how hard you press down with the nib, and it also depends on the type of nib you're using.
This is the nib & pen I normally use, and I bought it at an art supplies store - it's just a basic fine-tipped nib. I usually use it with black Winsor and Newton ink. :)
If you're unfamiliar with using pen and ink, the best thing is just experimenting with different ways of using the pen. Another good option is having a few sizes of nib to choose from, as some of them are finer than others, and some are designed for a particular thickness or type of line.
They've explained a few textures on
this page of the site you were looking at. Here's a couple of my pics for an example of some of the techniques they've mentioned:
In
this pic I've used hatching on the dog's stomach, and cross hatching (which is basically hatching from two different directions) under its chin.
For
this pic I used a less formal method - I made the background using a kind of scribble technique, mixing different types of lines, and using a slightly thicker nib.
Hope that helps! Either way, pen and ink is great fun, once you get into it! ;D
(Oh, and to see some REAL pen & ink work, check out Edward Gorey - his work is fantastic! ;D Click to see his
