Dear 100 Hour Board,
Is there a story behind the inside cover of the LDS Hymn Book? The one with all the swirly white patterns on the green back ground? I was fascinated by this page as a child and have always wondered what is was for and who designed it.
-The Manchester Hymnal
Dear Diamond Church Street Choir,
Actually, that kind of pattern isn't exclusive to the hymnbook; it's made through a process called marbling. I first read about the process in my brother's copy of The Dangerous Book For Boys a long time ago. If you're interested in learning how to make some marbled paper of your own, it looks like there are a few places online that can teach you how.
I looked at some hymnbooks to see if they were each individually marbled, and at first thought they might be because the patterns looked different, but upon further investigation I found that it's the same pattern for each book, just flipped upside down or horizontally or some combination of the two. Try it out for yourself and see!
