Layer Cakes.
 

Indeed ideas please for using a layer cake.

Walk in the city quilt pattern by Elisa's Backporch Design

There is a nice pattern from Jenny Doan of Missouri Star Quilt Store that uses a layer cake. It is very fun to make-it is a pinwheel and made so easily. I have made a few blocks with Christmas fabric. I think you may like it. Good Luck. Can't remember the full name of the block but Jenny has so many tutorials that are fun to make.

I made double-sliced layer cake a couple of years ago. Easy pattern and fun to construct.

How about moda bake shop?

Remember, you can cut a layer in quarters and end up with a charm pack! So look at those patterns too!
