hi Mary,
I use a cheap graphics pad 'Trust slimline' and I absolutely adore it.
It did take about 2 months to get the hang of using it, but I wouldn't be without it now.
I found it helped at first to hold the pen as close to the nip as possible, resting most of your hand on the pad, gave me more control over it.
I also did my drawings on a large scale using size 9 brush (12 ins or more), then went over the outline on another layer with a size 3 brush.
(The pencil produced to jagged an outline.)
Then I would reduce the image size to the correct size for print.
(I now use the freehand pen tool)
