Connie, looks like you're having a ball with your winnings, your cards are beautiful!
And a light box really does help with photo's - I have a nylon one that folds up and it's very inexpensive - it's almost always gray and rainy and overcast here so it's been a huge help for me. I have two cheap clip on lights at the top, one a regular light bulb (which produces warm tones) and one a natural daylight bulb (which produces cool tones). If you want to boost the light even further you can put tin foil over the lights so that it reflects it all back into the box!
