Have you tried Thread Treasures I think I saw something similar there.
Do you mean you need more of the same or more designs that would go with it. I have no idea where you could find that.
But a flower like yours is easy-peasy, just one 3/4 " petal repeated 8 times and that's it.
I wish my digitizing skills were up to that. I can add a circle here or there, that is about it. Since it is FSL I am sure it needs better understitches than a regular fill. I have some of the jargon, not enough of the discipline.
