Hemstitching?

I have just become interested, again in hemstitching. Hemstitching is the art of finishing the edge of fabric. In my case it is the finishing of baby bibs, receiving blankets, burpcloths, etc. I am ordering in some of these articles that have been machine hemstitched ready for the crocheting! I will be having a class to get people started learning how to do this beautiful finish. This image will show you what I am talking about. This may not be the best example, but you can get the idea. Noone in my area is providing this service, so I am hoping it will catch on.

I will have 4 booklets with different patterns for the crochet. Plus the crochet hooks and thread.
