Wrenkins what you need is a light box, and no I am not suggesting you go out and buy one. Think how you can make a temporary one at home. Take a sheet of glass, now think of a plate glass cupboard door that is not being used, so the edges are nice and smooth, and build up a little wall for the glass to sit on and put a small table lamp inside and then you can trace away to your heart's content.
When my daughter was a college (studying Art subjects) one of her friends made a light box out of a sturdy wooden drawer a short piece of cable with a light fitting on the end was placed inside the drawer and a piece of thick glass on the top. I actually have some plate glass cabinet doors (a pair) so I can use these provided I can find something to stand them on and leave room for a light to be placed underneath, or on my sewing cabinet, take the platform down to the bottom of the cabinet and put a lamp on that and then a piece of the glass over the opening at the top.
Failing any of the above why not stick what you are wanting to trace/copy onto a window and put your piece of paper over the top and again stick this to the window and trace away.
