Hi Aoife,
You might want to look at the GHD website its fab and features loads of styles and techniques in Video Form.
Go to www.ghdhair.com - Select Ireland from the menu - Go to the Trend Tab at the top - Select Looks and finally step by step techniques.
I know its a bit long going through all that but it is worth it. Very easy to follow and highly recommend the waves look espesh for summer.
