Welcome to the Quilting Board!
This is the first time it has happened to me, and I have copied multiple pages before without it happening to me. Just a fluke, I think, as when I went back to recopy the pages, it went to the same download that I'd used the first time.
We have a great tute on board by our own Alaskasunshine. She made it last year and I have been happily using her method ever since, I also posted photos of my shelf with fabric. Hope this helps I believe you will find her post with her board name.

I tried 2 different ways and actually like Kat13's suggestion with the ruler. Will send pictures later. Sewing room is a mess.
