Many thanks for the extra vid for joining lines. I presume you didn't find that forward slash in CS5 either?! The other way worked fine and here is part one. I'm desperate to start the cityscape but must alter something else first! So - back later...

Well, here goes. All I can say in my defence is that I made the cityscapes myself with the pen tool, which when you think about it, for me, is quite an achievement! And I had such fun. Thank you!!
