I just found this thread and have only read the first 10 pages, but promise to catch up. I hope this information is not redundant, but my favorite embroidery design site is:
http://www.oregonpatchworks.com/collections.php?id=HIA (HIA is a design team called Hatched in Africa".) Everyday you will get a listing for the designer of the day and the special. And there are free designs scattered within many choices. Sometimes the discount is 70% and the designs of many are just wonderful. Today she has designs for $7 for a grouping. Enjoy!!
