I want to make a 12 1/2" square block with a dresden plate in the center leaving about 2" around it. Can someone help me with the dimensions of the petals?

Thanks in advance!

I am working on a Dresdan Plate right now, using the Easy Dresdan Ruler. The directions on it says if you want your block to finish at 12 in. your wedges or petals should be 4 inches. That would make your plate 101/2 inches. Hope this helps you and good luck with your quilt!

Perfect.... that's exactly the help I needed. I really appreciate it!
