This cap I have crocheted for my doughter.
She is 2.5 years old now. Her head size now is about 47-48sm.
I`ve crocheted it of cotton,wich produce in Russia. The size of it is 100g/400m. I made a detailed tutorial in photos and posted it on my blog. You can find how to crochet this cap on http://glinchak.com/odezhda/master-klass-kepka-utochka-t8...
