This block places two large triangles in an hourglass shape, with a diagonal line of smaller squares crossing between them. It has a documented publication history: it appeared in Wallace's Farmer magazine in 1929, credited to designer Emma Tyrrell, who was working from a quilt already nearly fifty years old at the time she submitted the pattern, meaning the design itself likely dates to the mid-1800s even though the print record starts in 1929. Tyrrell's original description described the two triangles forming the hourglass shape, with the diagonal squares representing sand filtering through it.
