I found this today when I was looking at some paper pieced pattern that I thought would be interesting & helpful to many of you. I frequently want to reduce/enlarge patterns that I find & this looks like a great chart. I have not tried using the Adobe Reader but I'm sure it works well with that. My printer has a reduce/enlarge feature & that is how I do mine. I hope this helps you.
