There had been a library cart full of unwanted old books at school. I saw one on immigration and thought of my cousins who had immigrated to the U.S. It had the perfect amount of pages for me to fold the word "dream" so I took the book home with me and did just that. The hardest part for me was creating the plan of where on the page to fold and how many pages to fold for each part of the letter.
P.S. Yes, I did feel a bit guilty about folding the book, but the book is actually still readable; all I have to do is unfold the pages as I read along.
