The world of single skein knitting patterns is a little confusing.  As far as I was aware, the term "One Skein Wonder" was originally coined by Stefanie Japel for the free mini-shrug pattern she published on her Glampyre Knits website.  The phrase has since spread, either through a surfeit of catchiness or through a dearth of imagination.

Anyway.  This is the original One Skein Wonders, which spawned a series of other books by the same editor on narrower topics.  I have flipped through the sequels at the book store, and I still feel that this is the best.  I wanted it so that if I had a random skein of yarn on hand, I could figure out what to knit, and it fills that mandate well.  I don't feel that a targeted version like Luxury Yarn One Skein Wonders or 101 Designer One-Skein Wonders would do as well, although I could see why they might be handy.

One Skein Wonders is organized by yarn weight, which is somewhat diabolical.  The book is designed with the assumption that you have the yarn first, and you need to find a pattern for it second.  If you just want a book you can browse for, say, "an easy little hat" or "an easy little scarf," then this may not be the right book for you.

The patterns were submitted by a variety of sources, including a few top name designers, as well as some yarn store owners, and some people I'm not sure where they came from.  (I feel like I should be submitting my patterns for books like this.  But where?  And how?)  Although this gives you a wonderful variety of pattern, it also gives you some uneven lumps and bumps in the quality.

For example, just in flipping through I found the Scrunchie Hat which has you use Cascade 220 knit at 4 st/inch.  Cascade 220 is one of my favorite yarns, and I feel passionate about what I believe to be its correct use.  And that is not 4 st/inch, despite what the label says.  At 4 st/inch, Cascade 220 is limp and uninspired, and creates a dismal fabric.  It needs to be knit at 5 st/inch for most things; 6 st/inch where you really need firmness, as in gloves and socks.

This pattern is also in the "Worsted" section, which leads me to my next topic.  How do you know which chapter your yarn is in?  Only some kind of lunatic would consider Cascade 220 to be a worsted weight yarn. Although since the pattern calls for it to be knit at 4 st/inch (see what I mean? Lunacy!) then I can see how it would end up there.
Nevertheless, this opens the door to doubt.  Will I find other Cascade 220 patterns (knit at a sensible gauge) in the DK section?  If I have a skein of sock yarn, will I find a pattern for it in the Chunky section because it's for a lacy scarf knit at 3 st/inch?  Confusion!  Chaos!  Mass befuddlement.

This is a problem that could be solved with a bit more organization.  Let's say an index that cross references yarn with gauge and pattern number.  But we don't have that, there isn't even a listing by yarn name.  Instead we have an index that references patterns by type and technique.  So you're still at sea, I'm afraid.  All too common a predicament.
