I call this the "Pillowcase Finish", good for small pieces and very easy to do!
This next one I use the most - "Facing a Quilt". This takes me back to clothing construction days, doing facings on garments, grading the seams and understitching for a nice flat edge. That's what I'll be showing here.
It gives a nice clean, flat edge to the piece. For art quilts I prefer this to a binding because it is more non-traditional.
