Scraps. I had been given a book in a lovely green linen cover for my birthday when I was about 10. The book was Alice's Adventures in Wonderland. It was the first book I ever read myself and I treasured that book so much.
Then I discovered Scraps! Little paper pictures of all sorts of weird and wonderful things: Cherub angels, Father Chrisitmas, flowers, babies, crinolined ladies, birds, fairies - the list goes on. We would swap them at school and try to make 'sets' of every scrap available on each topic.
And I kept all my scraps in my beloved Alice in Wonderland book which I read over and over.
Lovely memories.
