Thank you everyone for all your comments.
When I choose the fabric, I choose the biggest prints with the most colors and go from there. Oriental fabric is beautiful for doing the Stack and Whack. It usually has some gold veins running through it. It makes a beautiful block.
Here are a couple more that I have made. One for me One for my DGD and one for my DGS. They are being quilted as we speak. I have had hand surgery this year so am unable to do such big projects yet.
