I make those magnetic book markers all the time, by recycling greeting cards. I get so many compliments on the gift. I give them for special anniversary's, birthdays, hospital stays and place them in some funeral cards too. I'm also a park greeter in Texas and make the book markers for gift bags. I give them to church for new church members. Great way to reuse the pretty greeting cards. This book mark, marks a last line read, not just the page. You place the book mark in the book sideway, on the part of the page you just finished reading.
