This is the book I used when I was learning to machine quilt. It shows how to quilt a rectangular quilt in a diagonal grid, so that the bulk of the quilt stays to the left of the machine. "The Complete Book of Machine Quilting" by Robbie & Tony Fanning" (

I use the Prismacolor Verithin colored pencils for marking my quilt, it washes out easily. I never use the scarlet color as it won't wash out, the rose is fine.
