First things first: this is a KNITTING book, not a needlepoint book. Many of the reviewers below have confused "The Celtic Collection" with "Celtic Needlepoint," which is a different subject entirely.
"The Celtic Collection" is my least favorite Starmore book. Alice Starmore's collections are usually about evenly divided among Fair Isle and cabled patterns, but the balance here is heavily skewed toward colorwork. If you're a texture knitter like me, this is not the collection for you--get "Fishermen's Sweaters" or "Aran Knitting" instead.
Sadly, the few cabled patterns included in this collection are just not up to par. One otherwise lovely Celtic-knot tunic is ruined by an ugly band of ribbing around the waist. Others come in only one size. This is especially disappointing, since Starmore usually provides directions to knit her designs in a generous range of sizes. The one sweater in this collection that I really would enjoy making and wearing would never actually fit me!
Alice Starmore's designs are renowned for their beauty and complexity, but the Fair Isle sweaters in this book involve a staggering number of colors--more, I think, than in other Starmore collections. The effect is marvelous, of course, but I can't imagine keeping track of so many yarns at once!
The ancient Celts are surrounded by layers of myth and legend, drama and hyperbole, and Starmore really does express this in her bold, flamboyant colorwork designs.
