Kass, awesome quilt you have going on there! Many years ago I took a stack and whack class at Martelli's in Pensacola, we made the 4 patch S&W. I have completely forgot how to do that method and even bought the Bethany Reynolds book. I'm so afraid to cut the fabric and have it ending up in a mess. Seeing yours I may just have to get that book back out and give it a whirl.
