Satin stitch is out, that much I know. I did just a satin stitch around a square on a tree skirt. (a class I took) I didn't like doing that at all. I could just imagine trying it on something this big. Ugh!
The quilt shop lady that helped pick out the fabrics said she would help me with a bias edging. I still like the ideal of what I call the pillowcase method, turning, as well. If anyone comes up any other ideals, I'm open. I still have the bottom half to do.
