Looks really good!!!! That quilting worked well on it, too.
8 pt stars on sashings are really easy. The Mary Ellen Hopkins method is to line up star point A with one sashing corner, then sew on the diagonal and fold. Be sure to hold/pin the folded piece in place. Then line up the square for star pt B with the other side of the sashing, sew and fold. I will try for a tut later in the week.
Once you have the quilt pieces cut out, most of the work is in preparing the sashing bits. This is not a hard quilt, but can be tedious if you do a big one.
You could cut and piece, like a standard flying goose block, but this works really well with muslin, as nothing shows through. I have used this sort of cornerstone on a number of different quilts as it looks much harder than it is.
