Alana, I think Molly is talking about points being cut off because of the 3" strip width. I had to adjust the strip to 2 3/4" x 8", then when I sewed the two block together I ended up 1/4" all around for joining other blocks without losing my points.

Hope that helps. I have some blocks in my Emily and Heather album that show Stack and Whack. Make sure you use starch and no steam, it will help a lot with piecing.
