Hi annia,
yes i remember Hildalgo well. all the beautiful ceramics there.
as for a quilting teacher, you could see if Fame has quilting classes. I taught painting through Fame when i was living there.
I also volunteered at a home for girls and boys called "Posada de Maria". it is still in operation but has since changed location. The idea was to teach the girls sewing (lots of quilting) as a way to get secondary income while they attended school. eventually most of the 13 girls got through college. They were girls from the countryside who would not ordinarily have had this opportunity. They now have a new crop of kids. It was very rewarding working with them and I remember those days with such fondness.
it's fun to talk to somebody so close to my ole stompin grounds! I picture you there in the nice sunny weather. (I am in cold michigan.) :)
