Thanks RC, and Jsprogg, RC: Cheers man, hadn't tried doing the whole measuring thing before, but figured it'd be the best way to make sure everything looks right in the end. Jsprogg: Haha, I had already wondered if that'll happen, but as two of the rooms in my house are occupied by other people thankfully I won't really have the chance to! Thanks for the kind words both of you! Haven't done too much more this morning, but got the window frame in, it was quite a mission to make all the different levels, and grooves etc, and get them all the right sizes, but got there in the end!
