Amy, be glad she chose an applique pattern from that book!
I tried a pieced Storm At Sea from a vintage book, and the pieces were laid out on a grid, and you had to enlarge from there. It turned out to be a train wreck! Thankfully I only tried one block before I cut all my fabric! Good did come of it. I found a place for some marvelous templates!
Good luck on your Mom's quilt and I'm sure Dad's shirt will come out just fine!
