Here is my daughter's Sheep Haiku, to get you started:
Come, sheep in your white
Coats of warmth, to my spinning
Wheel, to give me wool.
Peace on earth and good will to all! Meow.
The circular start is at the back of the book, but it comes along with a discussion of Pi Shawls (and other great EZ stuff.) Just think! For very little money, you can buy this book, see an excellent circular start AND try it to make a Pi shawl! What could be better? Maybe a doily, you say? Well try this: http://www.yarnover.net/thisthat/beginner.html
This website is owned and maintained by Nurhanne Reckweg, who has translated some of the best doily patterns on the Internet, and the above link takes you to some tips and tricks for doily knitting. While you are on her site, I suggest you look around and find the free doily patterns, which you can use with any of these circular starts. CAST ON!
12/15/07 Addition! Fleegle sent me this link: http://fluffyknitterdeb.blogspot.com/2005/10/knitting-made-easier-turkish-cast-on.html which shows a Turkish style cast-on. The selling point of this technique is that you do not have a hole in the center when you are done. This might be a good option in certain situations, and Fleegle says it is an easy way to negotiate just four stitches for a center start. I have only used this technique for starting socks from the toe and hats from the top, but I will try it for lace the next chance I get. Meow...
