[ATTACH=CONFIG]594470[/ATTACH] As a hand quilter from years back, l realized stencils are seldom the size you want. Just make a simple template ( cereal box cardboard will do, or plastic dollar store cutting mats), perhaps a pointed oval as in picture. Do the math. Draw one on paper ( fold/ trace) to get halves the same, then cut out paper, trace around to template material and draw a center reference line on the sashings. Use that to center your shapes. I always do the intersections first, then fill in, as you can fudge the fillers a bit without notice.
