I just whipped this up for my niece in a hurry. Very easy and she loves it. It's a disappearing 9 patch.

MSQC is my go to place when using Layer Cakes. She has so many different patterns to choose from and a video to help you be the most productive with your LC's. You will have a whole lot of patterns to choose from there.

My favorite is "Walk in the City" by Elisa's Backporch Designs.

I agree with the double slice, I don’t think there’s anything easier than that one.
