Yellowman,
I'm such a newbie to paint.net I'm still trying to make a straight line erase free hand. But I'm bound and determined to make me a sig like the one you seem to use the most; the torn piece of paper. That is so eye catching and to me shows a remarkably creative mind and with a firm grasp of how to get 'er done in paint.net.
If you ever decide to show a raw senior citizen aged newbie some of the tricks I will be pleased to accept.
