Comments: This is a BIG swatch.... about 10" x 8.5". Interesting note, the picture of this block in the book is backwards - the diagonal lines in that pic all run upwards to the left, even though the instructions clearly state that Row 1 is the WS, which means that the "front" of the work should be the side I'm showing here! I guess the photographer didn't read the pattern instructions very well. :)
