Hi Maureen, have a look on KO's designs. There are 2 Peony designs under the Flower heading. And I agree with Kim, just change your colours to suit what you are wanting. Love Chris
In the left hand column you will see a heading saying Large Peonies, go further down the list and you will see Peony 1 and Peony 2. Good luck with it all.
There are some Peony designs at Embroidery Library..i you find a design you like, there is nothing "magical" in making it white...just change the thread colors...and another design at Advanced Embroidery...but the link would not copy correctly...Google it..
