I love to knit toys and I especially like knitting these ballerina dolls (I call them Valerina's because my name is Valerie!) They are knitted from a Jean Greenhowe pattern book called Mascot Dolls. http://www.jeangreenhowe.com/mascot.html
They are stuffed with fibre fill and knitted on 3 mm needles. Red Heart Yarn http://www.coatsandclark.com/
and various Lion Brand Yarns http://cache.lionbrand.com/cgi-bin/yarnInfo.cgi?yarnPageIndex=1
are great for knitting the dollies. I hope you like them!
