Jon Yusof has recently published a trio of tatting booklets, "Elegant Tatting Gems" 2011, "Tatting with Rings (around Cabone Rings)" 2009, "Tatted Snowflakes Collection" 2008. Each of these half-size booklets is 8" x 5.75" (21x14.5cm). Both photos of the lace and the diagrams are in gorgeous color. See book reviews:

She also shares a pattern with us called Rose Window. This pattern uses all the basic tatting techniques plus the split ring, josephine ring and tatting reverse order double stitches (RODS.) It is also a good exercise to practice climbing out from a center ring through a mock picot into a split ring or a split chain.
