Much like the lace used on this one, I used what I call the Eleanor Burns method of using 1/2" rickrack on the curved edges. I'll have to look a bit for a link to the video I used.
found it in time:
And I will use what I am calling the Eleanor Burns method of using 1/2" rickrack for the curves, both for the fan blades and the pies. On the top side of the fabric you sew rickrack along your 1/4" seam allowance, I chose basic white. The rickrack is already bias and so you use it to help turn the curves. Then you stitch it down to the foundation block, first the fan blades, and then the pie piece. The rickrack will then add a textural element. Clear as mud, eh? LOL here's link to a video by Eleanor, the rickrack part starts around 18 minutes in.
