I think I may become addicted to making these little guys. These are from the new book Crobots: 20 Amigurumi Robots to Make by Nelly Pailloux.
This is Catbot.
Followed by Dogbot.
Babybot, who is featured on the cover of the book.
And last, but not least, Thinker!
I made all of these using leftover scaps of Vanna's Choice and Bernat Satin. They are slightly bigger than they should be because the book suggests using a sport weight yarn and a 2.75 mm hook. I was using about a 3.5 - 3.75mm hook along with my worsted weight wool. Since we don't have any small children in the house, I also cut corners and used a glue gun to attach all the beads instead of sewing them on, as the author recommends.
In short, the book is awesome. All the little robots (err, Crobots) are adorable and the patterns are easy to follow. I regularly review amigurumi books, so if anyone wants to check out my more detailed review of this one, you can see it here: http://cthulhucrochet.blogspot.com/2009/05/crobot-roll-calland-review.html
Thanks for looking,
