Those of us who are "dyed in the wool" knitters have been offered a treasure trove of spectacular books within the last 12 months, but this one, "The Principles of Knitting" tops my list of must-have volumes. Here's my take on June Hemmons Hiat's revised foundational volume:PROS:1. "Principles" starts at the beginning (e.g., how-tos, including knitting methods, cast-on, cast-off, selvages, and more basics) and proceeds to the most complex. She has included all the basics every knitter needs to understand.2. Many knitting writers stress the importance of starting each project with a gauge swatch, but this volume includes a series of photos of swatches made with different yarns and weights. We know (from being told so often) we should always make the swatch, but often we are so ready to get going that we skip this most important step with sometimes sorry results. Now you can see why you must do this before plunging right into your pattern.What was news to me is simple common sense that I have been woefully lacking - dress the swatch. Of course! It makes perfect sense that your swatch should reflect the same finishing that you'll apply to the finished garment. And that would explain why, sometimes, my garments do not exactly mirror my swatches.3. I've recently had a bear of a time picking up stitches to finish a hemmed neckline and hemmed armholes. My problem? Getting the picked up stitches exactly even on each side. Now I can do it with ease by picking up all stitches and decreasing as necessary - perfect! Why didn't I think of that before.4. Not everyone becomes an avid knitter, but, for those who do, the time inevitably arrives when they want to knit their own original designs. The Principles of Knitting is the definitive resource for designing your own knits without hiding the final product or having the neighborhood gather to giggle at your results. For example, consider the discussion on designing a sleeve cap (pp. 495-96 - available for you to read in the "look inside the book" section above). Here's a clear discussion on how to fit the sleeve cap so the results look professional rather than disastrous. Think about it. Shouldn't handmade knits look great (better than off-the-rack) as well as being heart-felt creations? This is the resource you need to make that happen.5. There's a ton of information in this book that I may never get around to using, but that's ok. There's so much to do differently in the techniques I already use, that I will be busy from now on - and my results will be even better. But if I ever get bored . . .CONS:1. This is a HUGE volume, so it is understandable that certain cost-cutting efforts were applied to reduce the final size and expense. However, the paper used is light-weight, and the print sometimes shows through the back of the page, making it a bit difficult to read. I consider this book an important tool, just the same as my hard-wood needles, so I would have preferred a heavier paper even if it increased the cost of the book. After all, the cost of the best tools usually pays off in the best results!2. A question: What's with the Kindle edition of this book costing 51% more than the print edition? How can that be reasonable? About the only advantage I can imagine is that you could receive instant delivery, but is that worth paying so much more?OVERALL:I pre-ordered this massive volume on September 1, 2011, and waited almost six months to read it. It was worth the wait. If I could own only two knitting books, this would be one of the two. The other? "Finishing School." With these two books, you'll have the answer to any "knotty" problem you might encounter. Knitters rejoice! This is the mother lode!
