"I'm 72 damn years old and am having brain farts - can't do the math. My book is 9\" x 12\". Can someone please help me figure out the dimensions of the jig I need to build. And thanks for this tutorial - I think I can do it if I can figure out measurements for my jig.\r\nWith much gratitude, Sandran"
