I found this fabulous and simple tutorial from Grand Revival Design for a ruffle skirt, bought the material at Hobby Lobby and went to it.
It was really easy and I finished in an afternoon. When I do it again (I already bought the material) I'll be adding an inch to each panel. It was a bit short for this mama.

I had to alter her design a bit because I could only find overall clips. To use them, I took an extra strip of fabric and folded it length-wise in thirds and sewed down the length of it. I looped it over the clip loop and secured it with more stitches.
I slipped it in to the tube (see tutorial link) and then did the top stitching around.
Since baby uses the Soother (which has no loops for elastic or ribbon) I used a clip on each side. Before the week is over, I hope to post a template for two different felt clip cover-ups, but in the mean time, I love this sweet fabric.
