Someone on the Cricut message board was looking for a magnolia cut file. Although there is a magnolia on the 50 States cartridge, neither the person looking for the magnolia nor I own 50 States. I decided to make an attempt using George.
I am going to say right up front that this is NOT my best design ever. Magnolia's are complicated! I used two different tints of white card stock, then highlighted my petals with my copic markers. I also hand-shaped my leaves a bit. I found three leaves to be plenty, by you may prefer more. Also, I ended up rotating my design 90 degrees after it was cut and I liked it much better.
