I've had this book for a long time, but I only took up knitting seriously in the past 6 months or so. The few patterns I knit out of this book were great - simple, easy to follow directions, and the resulting products (the ones I chose anyway) still look good after 20 years.
The problem though, is that almost all the yarn specified in the patterns are hopelessly outdated and have long since been discontinued. Try finding Pingoin Pingolaine or Maxwell Cartlidge Lotus Silk 4 ply today and let me know how you get on =_=. It's a bit easier with patterns done in stocking stitch, because you can attempt to find something with a similar yarn tension, but for anything done in pattern it's a lost cause. Accordingly I can't recommend this book to anyone except those who have easy access to discontinued wool or who are experts at altering patterns to suit their current material.
