At http://www.flickr.com/groups/tsunamiquilt there are some fine samples of embellished Crazy quilting.
For those of you that may be interested in this but don't have a clue of where to start I have collected some links.
Crazy quilting began at victorian times. Read some historical facts here
For embroidery I'll recommend Sharon B.'s extensive Stitch Collection. You can see very good quality pictures of each technique explained, and there are some stitch combinations for Crazy Quilting. Of course check her galleries for some eye candy (1, 2, 3 and 4), and her exhaustive blog for everything textil related. And of course you can see her contribution to the Tsunami Quilt here
... these links are only the tip of the iceberg, there are loads of information on the web, just try a search at google.com
