How do I put a face in a windmill sail?

Hi all

Our company logo consists of 3 windmill sails.

I would like to design a series of posters which use the outline of one of the windmill sails, but put an image of happy smiling people inside instead of the block of colour.

I'm sure I can achieve this effect in Photoshop, but I'm not sure how to go about it...anybody got some advice?

Many thanks

Lisa

Thank you RTW1 - that's so simple, but so cool!
