We normally announce the winner of a challenge each Saturday morning at 07:50 UK time - ten minutes before the new challenge goes live.
When you visit to get the new sketch, please scroll down to see if you are our winner from the previous challenge (or indeed if you are a new winner if the previous winner has not claimed the prize).
Also, please leave a comment on the winners post, this ensures that we know that you are aware that you have won, and also that we can expect an email from you.
It would also be polite to thank our generous sponsors for their wonderful prizes, don't you agree?
If your email goes to a spam folder (some may get automatically deleted), this means that we are not aware that you sent an email, this could result in another winner being chosen, and once a new name has been chosen we are unable to offer you the prize, sorry.
However, if you have left a message on the winners post, we will know that you want to claim the prize and can ask for your details again.
You have until 18:00 (6pm) on the following Thursday to claim your prize.
Thank you. xx
