Our ever-generous sponsor Simon Says Stamp is offering a $50 gift voucher as the prize again this week! The winner will be chosen at random from those who enter the challenge, so why not give it a try? At the very least why not head over to the Challenge Blog to see how the other members of the design team have interpreted this weeks theme! :)
