Hello Ruthie, Stippling is a freehand motion where you sew in as I teach like puzzel pieces, and you never cross a line of stitching. That takes a lot of practice but is addddddicting. The biggest thing is to breath. You can't do it if you don't breath. LOL There is stippling where you can cross the lines like stars or curlie q's or spikes and so on. It is used to make turpunto stand up real small or larger just to quilt a whole quilt.
Hope you can get the picture here. Sorta hard to explain... happy quilting.
