Yes, that is a great book. It has a wonderful technique to quilt with decorative stitches and also for joining the blocks. The sashing technique for joining the blocks can be used in any quilt. Right now I am using it to make a tee shirt quilt that I'm free motion quilting each square. Marguerita also has a fb page and a website with some videos.
The quilt on my avatar, Hawaiian Shirts Recycled, is made using her book.
