Good link here on how to photograph artworks.

Problem is that it looks like you could spend a fortune on getting all the kit to do it, but here are some money savers:

Greaseproof paper stretched over a frame makes a good light diffuser. Use a powerful desklamp.

You don't need a huge tripod - since you're likely to be taking the photograph on a table one of those mini tripods (the size of a handspan) should be good enough - or just balance the camera on a pile of books and use the timer to take the picture so you don't get camera shake when the image is taken.

I'll look into posting a 'cheapass' version of this tutorial which will require a compact digicam and stuff you can find around the house.
