Changing thickness of a pen line

[ssidetv]

I am new to Photoshop and keen to learn how to make some lines that I spent a LONG time creating, using the pen tool then Stroke Path with too wide a paint brush. I do not wish to recreate the various lines, so I figure I need to make a mask to overlay and thereby reduce the the width of the line. But I don't know how!
Can someone please give me a workaround for this?

Thanks,

Nick

You still presumably have the paths, so just revert to the stage you were at before you stroked the paths, change the Airbrush size and re-stroke the paths. The paths will be stoked by the brush, colour and operation you have prior to the stroke paths command, so it's best to get into a routine of setting up your tool first - if it's not right simply undo, change the toolsetting and go again. Hope this helps - I'm not exactly sure how much work you did before you the stroke action,
