I'm trying to crochet this Granny hexagon, managed the first two rounds but am really stuck with the third. First of all I don't know how to join the different colour (don't usually have a problem with this lol. Then I just don't get the 1st bit of the 3rd round. I've tried several times, made a peculiar join but still couldn't manage the next bit. It's probably easy but I just can't see it. Any help appreciated. I'll put a pic up of the hexagon too.
