Hi What is the difference between One Block Wonders and Stack and Whack? It's amazing how the cuts totally change the original fabric.

I just purchased the one block wonder book

I did too and cannot wait to try them out even withing the instructions there are different ways to cut!

OBW's are a hexagon block
Stack and Whack can be a 4 patch or more identical pieces in different shapes :D:D:D

OBW can be either hexagon or octagon. The quilt's center usually has only one fabric, unless hollow cubes are incorporated into the design. Stack and whacks usually have sashing and use two or more different fabrics. Both are cut by carefully stacking fabric so that the design elements are lined up through the various layers.

Stack and Whack - books by Bethany Reynolds

Stack and Whack has been around longer.
