The Wiggly Wave Ruler
Initially I thought...oh, not another wave! ...but, there are some cool things you can do with this one
First try
How cool are those semmingly overlapping lines! Can't lay claim to that idea, saw it on the Handiquilter Ruler of the Month Club 5 video. Also really liked the first design on the right, one line stitched out with the ruler and then the first and third line freemotionquilted with a circle in it around it. that would look really nice in a narrower sashing.
