What is the best method for Curly Hair Extensions?

I have decided I am going to get hair extensions, but having done so now I find that I am having a hard time finding curly thick light brown hair that is quality and will blend with my own. I also here about so many methods for installation and for every recommendation there is an opposite opinion. I am hoping some one experienced in curly hair extensions can give me advice and maybe recommendations as to where to buy this hair etc...
