Thanks for all the tips, I think I know what to sew now. Will post the result when finished.
Here is a website with Bulgarian symbols and motto...sorry it doesn't help much for embroidery designs but perhaps it will give you an idea...
That is all I could find. Maybe by seeing the picture of the flag you could recreate it with ribbons or by sewing.
