Tunisian Crochet Stitch Guide

I bought this book to brush up and expand my knowledge of Tunisian crochet and I am very disappointed in the book. The book does have 61 stitches in it and they are each numbered and that is the issue. In patterns and in application of stitches the types of stitches are not called by numbers such as Stitch 7 or 11. In patterns and the real world you have Grapevine and Seed and Keyhole Lace stitches.....these stitches might well be included in this work, but I would not know since the only stitch names used are the very basic ones, TSS, TKS, and TPS.
