Here is a fun and unique quilting design that you can do with a walking foot. It is the orange peel (also known as the cathedral window) and Pippin Sequim shows us how to do it.
The article has diagrams that take you through the entire process, beginning with sketching out your design to stitching it. It even includes the sequence of how it should be stitched.
This pretty design would look lovely on so many different quilt patterns and it really is not that difficult to do.
If you are interested in adding another quilting design to your repertoire, then this is a good one to add. You can find it here: Orange Peel Quilting With a Walking Foot
