There might be something at CinDes Embroidery Designs...

Go to Embroiderydesigns.com and type in Mexican folk dancer, there is a lovely design on there.
On Embroidery Library there is a great set too. Type in "Talavera Design Pack - Lg". Love Chris
I love the folk art designs at Urban Threads and have used them a lot, particularly the Las flores set.

Since I can not imagine what your project is. I can only suggest to google for either
Mexican embroidery designs or
Mexican folk art embroidery designs.
Maybe someone else will come around and will be able to help
