I found a BUNCH off of yahoogroups.com where I looked in machine embroidery...you can get all kinds of advice/designs from there www.marvelouscreations.com
is another site with some designs and a GREAT launch point as well (I've ordered needles from him and he WAS GREAT!!). Very cheap!!
Try doing a google search under machine embroidery designs and see what you can find. I used to work nights and surfed alot but now I'm a stay at home mom and don't have much time
If I can help any more, please let me know!
