I watched the lessons and then I tried to do it on my own the next day. Next time I will try to do something completely different and more personal. It was not easy to manipulate and do the collage. But now I got it :) I used an electric wire and it was ok.
I used the space under the card to put some photographs of my niece and me as it was a card for her.
I'm very happy with the result and I'm sure next time will be better.
