Hi Neil, wlcome to the forum. There is loads of info on here, all you have to do is tak what you need from the various posts and run with it, when you get stuck post your disasters and your sure to get feedback an ideas on where you went wrong and how to sort it ... before you know it the pennys dropped, things get easier and your off and running freestyle ..
Everyone on here has been there with shaping problems, so dont hold back on pic posting there is a lot more to be learned sometimes from seing problems and reading the solutions than seeing pics of finnished stuff, finnished stuff is good as well though... enjoy
