Though better known for her embroidery and embroidery books, Wilson was also a master knitter. Into her one knitting book she worked explanations of all the important knitting techniques, plus embroidered embellishment, with plenty of practice pieces in the form of classic-yet-arty knitted sweaters and accessories. Because they're classic, if you are a person who likes wearing classic-shaped sweaters and/or knitted shawls and/or lace collars, you could still wear these pieces.
The Knitting Universe underrated this book, in the 1990s--I suspect because of production issues. While Wilson was a TV star every public library seemed to have ordered a copy of her book. Though pretty, the books weren't well bound, and as the knitting boom of the 1990s got going those books disappeared from libraries due to an unfortunate tendency to fall apart. (I bought two copies; both tend to lose the same pages. If you can find a copy with all the pages still together, you're lucky. Handle it with care.) They would have been worth reprinting in a more durable form, but with so many new knitting designers producing so many new pattern books, this one faded off the scene.
I made a "Jazz Sweater," following the pattern in this book, in 1990. I made it of some end-of-the-season-sale mohair yarn and didn't expect it'd last thirty years. But it did. I can still wear it with pride.
