Hi I am sorry nobody has got back to you, the best way to send in your work is as follows-
1. Scan it and send it as an attachment to an email (save as a Jpg)
2. Or you could photograph it, but to do that you would need to know how to correctly use your camera as the exposure (brightness) would need to be correct. Once you have done this you would need to transfer it to your computer and then save it as a Jpg. Then send the image as an email attachment to us.
The second option is more difficult but have a go and see how you get on should you need any further help then please let me know.
