At the beginning of all the Harmony Guides there is a very good and clear introductory page with all the techniques you need to know to create any of these stitch patterns. Whether or not you are a beginner or experienced.
There are plenty of stitch patterns to choose from edgings, lace, lace panels, cables, rib, knit and purl.
The photographs for each stitch pattern are in colour. There are no charts in this particular book, but there are written instructions, but you can easily convert them into charts if you wish using graph paper. The Harmony Guide 250 Creative Knitting Stitches does have Charts as well as written instructions.
These guides are wonderful just to browse through and knit a swatch or two, which I have done and there have been no errors, to see if it is suitable for a particular garment you would like to create.
As there are no garments to knit in this book I would also purchase The knitter's Handy book of sweater patterns and The Knitter's Handy Book of patterns both by Ann Budd to compliment these guides.
I have collected most of the books in the series and found them good value for money and an asset to my library.
