Half way through sewing one of the purses, I found myself wishing I'd worked out a long time ago, how to do a zippered pocket. So before I started sewing up the second purse, I got my camera out and took photos of all the stages to make a tutorial. I wasn't too sure how to describe the pieces, so I hope the photos speak for themselves.
Here is the tutorial for making a coin purse with an inside zippered pocket: http://www.flickr.com/photos/zedster01/sets/72157626049445520/
