Unfortunately I don't have the funds to invest in a lot of new photographic equipment (a proper DSLR camera will have to wait until another day!) so I have no option but to just do the best I can with my little point-and-shoot. Luckily, there is a lot of good advice out there in www land and I recently happened across a step-by-step guide to making your own light box. So, make my own light box is what I did and I have to say I'm pretty pleased with the results.

It's not perfect, but it's a start. Plus it will give me a lot more scope to play around with different coloured backgrounds etc.
