This is a linear design, so you'll either need to mark your quilt top for this design, or FMQ this design on a quilt with lots of patchwork that you can use as your lines. For the photos in this tutorial, I created a small quilt sandwich, and drew lines with a ruler and a Frixion pen. Frixion pens are handy for marking because they disappear when heat is applied, like from an iron.
Before I try any new FMQ style, I always doodle it a few times with a Sharpie to get the hang of the motion of the stitch. A quick warning: I doodle the opposite direction the I stitch in. I doodle from left to right, just the same way that I write. But I quilt from right to left, so just keep that in mind when following this tutorial. To doodle this design, simply follow the arrows on the diagram below.
