Did you go through the tutorials I gave you? They're very easy to follow.
 
If you want someone else to make them, make a request in the Graphic Mutual Aid section.

If you are not used to it, it does take a while to learn it.  But it is very worth it in the end.

Once you get it down and all the things you can do with it, you will wonder why you didn't try it earlier.

I was also stumped on the pen but now I use it for everything.
