There's a couple here on Cute than can be voted on for free, if you like one, you can PM Letvia and we'll try to vote it in for you. I'm sure somebody will have some other sites you can go to as well. Good luck, Marji

Emblibrary has some, but not free and embroidery designs also has some, but they aren't free either. Just do a search at both sites and the designs will come up. Teresa's embroidery has one small one which is free. Don't whether this will be the right size and I don't know about the quality, I'd suggest test stitching it first if you decide to use it.

The embroideryrn has a couple, you'll need to scroll down. They are in borders but you could use one.
There is one here in Designs by Cuties I brought it to the top so you can find it easily. It's small.

The stitchery mall has several for sale. Just search "crown".
